At Desiccant Dryair we manufacture a range of special units that come into the standard range of products. This is to say that the parameters of the dehumidifier air handler are special in the fact it has dehumidification, humidification, heating and cooling facilities all within a single cabinet.  It is standardised in the form of cooling and dehumidification capabilities and other functions.  It is not designed specifically for the customer.

The MTHCU dehumidifier has the following capabilities:

Airflow rates 75 m³/hr to 5000 m³/hr
Maximum ambient conditions 30.0°C @ 23.0 g/kg
Temperature range off 10.0°C to 60.0°C based on max ambient on
Humidity range off 10% RH to 98%RH @ 40°C

The MTHCU desiccant air handling system is designed for small climatic facilities that require very good control.

The controls engineering that has been applied to this dehumidifier air handler is extremely complex but this enables the unit to hold very close control of temperature and humidity. The control is offered with a PLC complete with touch panel human machine interface.

The control system allows for full remote access and integration into existing BMS systems.

All components that are required to operate such a complicated unit are within the package. This includes a desiccant dehumidifier fully modulated, a fully modulating direct expansion refrigeration system that allows the system to reduce cooling demand on request from the customer.  An integral re humidification system that can raise the humidity in a split second and heating systems including thyristor control modules for fully modulation control. 

The MTHCU is manufactured to the highest specification in 304L stainless steel as standard. We can offer 316 as an optional extra.

We have sold many of these units around the world to various companies for climate testing of components prior to use. The industries this unit typically serves are the Motor industry, pharmaceutical, agriculture, food, clean rooms, electronics manufacture and repair to name just a few.

They are incredibly reliable, accurate and have proven to be an asset to the companies that have bought them.

MTHCU models are available to download from our website.
