Our customised devices are primarily used in the process air area for use wherever conventional devices in the field of technical building equipment cannot provide satisfactory solutions. In addition to a wide service range, our air-conditioning units can take into consideration customer-specific factory standards or specific hygiene requirements.

We can already cover a wide range of services with our standardised designs, the LK, LKTA or LKL process air coolers. We also offer sophisticated solutions using sorption dryers.

Our process air coolers (LK and LKTA) are characterised by very low air pressure losses and are ideal for air cooling and air drying of pneumatic conveying air flows. Of course, other applications are also possible.

The process air cooler (LK) is filled with a water-glycol mixture, which is either supplied by the customer or by a WEISSHAAR liquid cooler.

Our compact process air cooler units (LKTA) are always used wherever individual process volume flows are to be conditioned and no refrigerant (e.g. water-glycol), which is supplied by the customer, can be used. The refrigeration is integrated directly in the LKTA process air cooler and ensures stand-alone operation of the chiller without additional costs and thus without the associated assembly. Depending on the condition of the machinery room, we can offer our LKTA device as a split unit with an external air-cooled condenser. The condenser heat is then discharged outside the machinery room without adversely affecting the building's air-conditioning system.

Our air-to-air cooler series (LKL) is primarily used for pre-cooling a compressed process air flow. The compression heat can be initially discharged to the outside air using an air-to-air cooler in an energy-efficient manner and without supplying expensive cooling medium. If additional cooling is required, a corresponding after-cooler is installed, whose load is efficiently reduced by the upstream air-to-air cooler, depending on the ambient temperature.

Please contact us about how to use the valuable waste heat of this process air. We have implemented a high number of beneficial heat recovery installations.

With low dew points (<4°C), an additional drying step is required in addition to the traditional cool drying. After the pre-drying stage, the process volume flow passes through a sorption dryer, which is already integrated in the system. The sorption dryer consists of a rotating drying wheel which contains highly hygroscopic material that binds moisture from the air.
