Protech’s cool water recirculators are specially designed for the adoption to scientific and laboratory instrumentation applications. These units are completely self-contained, consisting of a hermetically sealed refrigeration compressor, a water tank, a water pump and an electronically automated control system for supply of constant cooling water at the required temperature, pressure and flow rate.

Using refrigerated chillers that use water in a closed circuit offer many advantages over free flowing tap water for cooling instruments/machineries.

There is no need to have a water source and no need for drainage at site. Machine operation is not AFFECTED by water supply.

There is better temperature and pressure control thus improving operation efficiency.

There is no scaling problem as compared to using raw water as the cooling medium. Scaling reduce heat transfer and restrict/block the flow in the system.

Ease of installation/ set-up
• Fill the storage tank.
