Kelvion Goedhart Customized Air Cooler ZGB ZGZ

The Goedhart ZGB/ZGZ range is part of our customized industrial series. The advantage: A very high degree of customization is evident. Circuits matched to application give great performance and the optimized heat exchanger geometry have a greater specific output of the heat exchanger. This High Performance Air cooler is available for both air flow directions (draw-through and blow-through). As a result, the Goedhart ZGB/ZGZ can be flexibly and effectively designed for individual refrigeration requirements – especially for complex applications.

The coil blocks have steel tubes and steel fins hot dipped galvanized and are suitable for NH3, CO2 and Coolants as a cooling medium. All air cooler coils are pressure tested to 40 bars and supplied with a light overpressure charge.

Advantages

High performance due to application-suited circuit design
Variable air direction of all fan variants
Long-term assurance: highly efficient, ErP 2015 fans
Customize the air cooler with many available options and accessories
Flexible power spectrum due to a numerous of variants and configuration possibilities
Higher specific power, reduced fan speed and air velocity through the coil and significantly reducced current consumption
