With a cooling capacity of 3.9 kW the air conditioner of the PAC series is especially well suited for large rooms of up to 130 m³. Apart from the reliable cooling on hot days the PAC 3900 X filters and dehumidifies the room air and generates a fresh breeze to top it all off. As desired in three fan stages and with swing function for an optimal distribution of the air in the room. Functions of the PAC 3900 X The PAC 3900 X comes equipped with a modern microprocessor control and a variety of individually programmable functions. Optionally, the device regulates the room climate autonomously.

Temperature controllers of the teco series cd are designed for the operation with water and direct cooling up to 95 °C or 120 °C. The temperature of the process water is controlled automatically. A temperature sensor, installed inside the unit, measures available actual temperature. The microprocessor control with membrane keyboard or touchscreen operation compares measured value and preselect set value and controls heating or cooling. A trouble free operation is guaranteed by a complete safety system.

Our gwk engineers are passionate about developing technical solutions and this is what we as manufacturers want to prove in the area of cooling towers with our gvk/ghkv series. We see it as our task to understand the entire process of our customers. Therefore we have focused on quality and longevity for the products gvk/ghkv. The cooling towers are part of a central cooling tower system, supplied turn-key and regulated with a freely programmable microprocessor control system or programmable logic control. They are used for dissipation of excess heat from production systems with a higher temperature level and they operate on the principle of evaporation. This is an important consideration for environmentally conscious industries.

The patented gwk solution includes cold water temperature controllers that can be operated without glycol in the temperature range between 0 °C and 25 °C. The user can select between two models that are differing in cooling capacity and flow rate. A precise microprocessor control with simultaneous indication of nominal and actual value, the simple one-touch operation, optional interfaces at the front panel and external sensor connection, splash-water proofed electrics and the cabling with CEE-socket ready for connection make the unit ready for immediate use. Leak stop operation, mould draining, acoustic alarm, automatic filling and top up, additional manual filling possibility for conditioned water, strainer in the cooling water connection and parts out of corrosion resistant materials that are in contact with the medium are part of the comprehensive standard equipment.

Impregnation systems to close micropores in metal castings as well as in copper, aluminium or magnesium alloy castings. The parts to be impregnated are fixed in baskets. The latter are transported by a special crane system as well as with reservoir roller conveyors. Excess material is removed by centrifuging of the baskets. The impregnating agent remaining in the pores in fluid form is hardened by heating in a hot water bath. The process sequence runs fully automatically under a microprocessor control.
