ERT Refrigeration Technology GmbH products

We supply single circuit systems with built-in circulation pump for connection to heat exchangers or cooling tanks, in air and water cooled design. Also available are single circuit systems with refrigerant evaporator and agitator in a storage tank for high temperature constancy and different water circulation rates, including circulating pump.

The VXC is a pressure principle radial counterflow condenser with a tube bundle design according to PED 97/23/EC for a capacity range from 60 to 6,920 kW (nominal R22 kW for single cell models). They therefore supply the full nominal thermal capacity for a wide range of requirements as well as for various refrigerants. VXC models are suitable for indoor installation and occupy minimal floor space. They are highly reliable throughout the year and are ideal for noise sensitive environments.

Warm process liquid (1) flows through a heat exchanger coil (2) which is moistened with water by the spray system (3). At the same time, the radial fan (4) blows ambient air from bottom to top (5) through the tower. During operation, heat is transferred from the tube bundle of the internal circuit to the water and then to the atmosphere, while part of the water evaporates. The cooled liquid then leaves the unit (6). The tower tub (7) or basin collects the remaining water. The spray water pump (8) lets the water flow back to the spray system. The warm saturated air (9) leaves the tower via the droplet separators (10), which remove the water droplets from the air.
