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.
• Connect the power supply.
• Make the hose connection to the equipment

• Save costs
• Increase productivity
• Eliminate scaling
• Increase flexibility
• Conserve resources
