TUNDRA Water-Cooled Chiller

The correct capacity is based on the process’s actual heat load rather than only the sum of machine power. Inlet and outlet water temperatures, flow, simultaneity, production time, load changes and future capacity growth are considered. Oversizing can cause inefficient low-load operation and frequent cycling, while undersizing can prevent the target temperature from being reached. Compressor count and capacity stages are therefore configured around the real load profile.

The water-cooled condenser lets compressors operate at more controlled and lower condensing temperatures than air-cooled systems. Reducing compressor pressure difference lowers electricity use and raises COP. High-efficiency heat exchangers, staged capacity control, variable-speed pumps and optimised cooling-tower control together support high efficiency at full and partial load.

The cooling tower is not selected only from nominal chiller capacity. Total heat rejection equals the process cooling load plus compressor electrical input, so tower capacity must be higher than chiller capacity. Total rejection, local design wet-bulb temperature, condenser-water inlet and outlet values, flow and water quality are assessed together. An undersized or dirty tower raises condenser pressure and energy consumption.

Yes. Integration can be planned after technically reviewing the existing pumps, cooling tower, buffer tank, piping and building automation. Flow, pipe sizes, pressure losses, available tower capacity and system water volume are checked. Pump upgrades, hydraulic balancing, a plate heat exchanger, buffer tank or automation update can be applied where needed, allowing stable and efficient operation with the existing plant.

The TUNDRA Series serves high-capacity industrial process cooling and central air-conditioning requiring stable water temperature and uninterrupted operation. Applications include injection and extrusion, food and beverage, pharmaceutical and chemical plants, automotive, metalworking, textile, electronics and energy. It also serves central systems in data centres, hospitals, production campuses, shopping centres and large commercial buildings. Its 30–4,000 kW range supports both individual processes and central plants serving multiple lines, with compressors, refrigerant circuits, hydraulics, automation and redundancy configured for site conditions.

At critical production sites, TUNDRA can be configured with multiple compressors, independent refrigerant circuits, duty/standby pumps and multiple chillers so the system continues at remaining capacity if one item is unavailable for maintenance or failure. Where production cannot stop, N+1 redundancy, automatic sequencing and run-hour balancing can be applied. The required level is based on minimum plant capacity and acceptable downtime.
