Industrial condenser dryer DH 300 BY

Very powerful low-temperature dryer for operating ranges to -15 °C

The DH 300 BY is the ideal drying solution for all industrial production and storage environments requiring low dew points and large amounts of dry air.

This powerful low-temperature dryer was especially developed and equipped for fully automatic, hygrostat-controlled permanent drying applications in an operating range to -15 °C:

The automatically controlled cycle inversion enables defrost phases in a short period of time even in low-temperature operation and thanks to the plastisol-covered housing made of galvanized sheet steel the hardwearing construction is just as optimally protected against corrosion and other external influences of wear and tear as the additionally polyester-coated evaporator and condenser.

This makes the DH 300 BY the first choice in many industrial fields of application for reliable and economic permanent dry keeping or dehumidification.

Its long lifetime reduces the total costs of ownership and an active utilization of process energy – e.g. to generate hot water – helps to shorten the payback period.

The DH 300 BY is optionally also available in stainless steel and with high-pressure fan.

The stainless steel version is especially well suited for dew point reduction in particularly hygiene-sensitive surroundings, e.g. in the food production and in fermentation or storage cellars of breweries – but also for the dry keeping of waterworks engineering facilities or other spacious unheated industrial environments.

Beyond that, many other accessories are available to adjust the DH 300 BY to your individual requirements. We're happy to be of service!
