Emergency cooling ensures the uninterrupted supply with cool air

Avoiding losses of revenue

Interruptions of the cooling supply produce additional costs that even culminate in losses of revenue

Refrigeration technology, air conditioning systems and air conditioners have become indispensable items of our everyday life. Many areas in production, storage, but also in food supply and catering require permanent cooling. If the cooling system installed fails, quick support is needed. In a cooling emergency, Trotec is your quick and reliable supplier of mobile replacement cooling systems.

The following examples illustrate how dependent we are on reliable cooling systems and air-conditioning technology in our everyday life:

In a laboratory building the delayed refurbishment of the air conditioning system will temporary interrupt the cooling in the individual storeys. In a hotel business the cooling system, in spite of having been refitted, may nevertheless be facing collapse due to high outside temperatures. In the server rooms of a computer centre, heat loads accumulated by a failure of the air conditioning system are no longer dissipated. 

A failure of the cool air supply always takes you by surprise and definitely at the most inconvenient of times. Quick and reliable emergency cooling is ideal, for example, for the following application purposes: temporary accommodation, food and beverage businesses, computer centres, server rooms, storage facilities and production halls, measuring and regulation centres, laboratories, trade fairs and exhibitions, offices and commercial spaces, marquees ...

Trotec supplies speedy replacement in cooling emergencies

Cooling issues often result in production interruptions and consequently in substantial losses of revenue or drops in sale. Or, even worse, considerable additional costs caused by warranty claims and contractual penalties. Therefore, if the air conditioning system fails or if it is to be switched off for the reason of annual servicing, mobile replacement must be provided as quickly as possible. That's why the most reasonable thing to do is to take the event of a cold air supply failure into account in the first place – and also budget the uninterruptible cooling supply of professional emergency cooling like that offered by Trotec: Throughout Europe with express delivery thanks to the 24-hour emergency service, on schedule, with reliable, certified forwarders

There are many reasons why you might need mobile supply with cold air

Sudden failures, maintenance work or refurbishments are usually the main reasons for being in need of mobile supply with cool air. For instance, if the cool air supply system fails, because the air conditioning system of an office building or a storage hall suddenly is 'on strike', the in-house technical service may be able to remedy the fault. This could prevent a major production breakdown or a heat accumulation in rooms or halls. The situation may be different if a cooling unit shows such severe defects that only the replacement of the parts affected would be the solution. Then a waiting period for the replacement parts of at least a few days is inevitable. To ensure that the cooling supply is maintained nevertheless, mobile emergency cooling is required.

Another reason to revert to mobile cooling units from Trotec as an intermediate solution may be delays in the new installation of the stationary air conditioning system. For example, if a company decides on the installation of a new cooling unit or air conditioning system, in spite of the most careful planning, delays that are caused by the large number of trades involved and that can no longer be compensated later on are prone to occur. If you wish to effectively utilise individual building areas that are already to be supplied with air conditioning although the central cooling supply has not been installed yet, don't hesitate to call Trotec.

Mobile air conditioning
Emergency cooling of server rooms

You data also love to stay cool 

Did you know that the ideal temperature for server rooms is between 22 °C and maximally 25 °C? Especially in summer, though, it is relatively difficult to reach this temperature. For one thing, because the hardware itself produces a great deal of heat. As the permanent processing of large data volumes consumes a tremendous amount of electrical energy, which flows back to the server room as exhaust heat. If the outdoor thermometer additionally moves near the 35 °C mark, even modern server systems will get too hot. A heat-related server failure is imminent. If companies are struck by such a failure, everything stops – until the subsequent inevitable cost explosion that will erupt for repairing the damage. At high summerlike temperatures you should therefore rely on an additional mobile air conditioning system from Trotec – as the best protection against expensive data loss.

Winter time is servicing time 

To ensure that stationary cooling systems can also perform at their best in the next hot summer, regular maintenance is indispensable. The perfect time to perform such a thorough check of your cooling units and air conditioners is the start of the year, because then outdoor temperatures remain at a relatively constant low level. Since the low outdoor temperatures reduce the operating time and the performance to be reached of the mobile replacement cooling machines.

Mobile air conditioning systems of the PT series for easy and quick deployment

The mobile TROTEC cooling units of the PT series from European high-quality manufacturing have been specifically designed for the temporary cooling of large rooms, halls and marquees. The high-performance and reliable cooling units convince by their easy and quick start-up in almost every location. Whether you use a PT 4500 S, PT 6500 SPT 15000 S or PT 23000 S – depending on the model, the professional air conditioners with their cooling capacity of 5.5 kW to 27 kW can put through an air volume of 550 m³ to a huge volume of 5,400 m³ per hour. In this way, even large rooms are cooled down to 10 degrees Celsius in a short time.

Connecting as quick as lightning thanks to water cooling circuit with quick release fastener

The air conditioning systems of the PT series come with two separate cooling circuits. The refrigerant circuit of the basic device is hermetically sealed. By contrast, another circuit is installed between cooling unit and external heat exchanger for cooling the condenser as well as for heat removal using a connection set. In this additional circuit only water with a low glycol concentration circulates as cooling medium, thus ruling out a loss of refrigerant when connecting or disconnecting the devices in a professional fashion.

For a quick installation of the water and power lines between air conditioner and heat exchanger the connection sets of these air conditioning systems come equipped with high-class quick-lock couplings. As a result, even longer connections over a distance of up to 30 metres can be realized without difficulty in a quick, clean and easy manner – ideal, for example, for control centres, storage, server and utility rooms, where there is hardly ever any room to accommodate such heat dissipation measures.

With their compact dimensions and the practical transport wheels the mobile air conditioners of the PT series fit through normal doors and lifts. Trotec offers the right model for every specific application, as a variety of versions and performance classes of the PT series is provided to you.

PT air conditioners
Higher versatility by Duplex Cooling option

Higher versatility by Duplex Cooling option:

For all PT air conditioners, furthermore the possibility of using Duplex Cooling is provided. Instead of one heat exchanger, two heat exchangers are installed in series for each DualHex coupling on one connecting line in each case, i.e. the number of heat exchangers used is doubled.

Duplex Cooling allows for a Δt- increase of the upper working range limit value around 7 °C, which makes it possible to utilize the devices even at higher ambient temperatures, or ensures that they do not run under full load at lower temperatures.

Models for high-temperature environments up to +55 °C available

For warmer environments the standard models can not only be optionally enhanced via HEX upgrade or Duplex Cooling with ΔT +7 °C, with the PT 6500 HT and PT 15000 HT models, furthermore two special air conditioners are provided, which are specially designed for high-temperature environments up to +55 °C. In this way, PT air conditioners can even still be reliably used for cooling applications in environments so hot that other models wouldn't make it.

PlanoPT – the world's unique connection feedthrough underneath doors

TROTEC’S exclusive PlanoPT which is only exclusive available at TROTEC and TKL makes it possible to implement a quick and easy installation of the connection sets underneath doors between the inside unit and the outside unit of all PT air conditioning systems.

Then you can shut the door behind you – since, thanks to PlanoPT and owing to their especially flat centre part the connecting lines between the cooling unit and external heat exchanger of split air conditioning units can be practically installed underneath all common inside and outside doors. For this purpose, quick-lock couplings, plugs for the power line and condensate hose connection as well as earth connections on both sides of the PlanoPT are provided. The flow design of the watertight multi-chamber system has been optimized specifically for the flow rates of PT air conditioners and – despite the centre section's height of only 6 millimetres – it guarantees a smooth and uninterrupted pass-through without counter-pressure.

Rely on engineering skill "made in Germany" patented by TROTEC – your company will benefit from this installation underneath doors in both energetic and safety-related respects. Since because PlanoPT does not affect the closing characteristics of doors, the outside doors of event rooms, for example, can remain closed. Contacting Trotec may therefore also be your perfect solution where this subject is concerned.

What cooling capacity do your rooms require?

For business facilities, surgeries, offices or warehouses, you can use the following values to carry out a quick and approximate determination of your demand for the cooling capacity required:

  • 30 watts per cubic metre
    for ideal-typical business facilities along the lines of passive house standard, normal sized window area and little frequented
  • Additional 10 watts per cubic metre
    in the case of poor insulation
  • Additional 10 watts per cubic metre
    if there are more than 3 individuals in the room
  • Additional 10 watts per cubic metre
    if the size of the window area exceeds the average
  • Additional 10 watts per cubic metre
    if the windows and/or outer walls are facing south
  • 50 watts per cubic metre
    for attic rooms.
    Especially for attic rooms in old buildings determining the required cooling capacity remains a difficult task due to the lack of knowledge regarding the roof's thermal insulation. Just to be on the safe side, 60 watts per cubic metre as a basis, in the case of poorly insulated roofs and many skylights, still more.
  • 55 watts per cubic metre
    when using air conditioners in construction site trailers
