Digital Temperature Controlled Recirculating Water Chiller with 75L/min Flow, 30K BTU/hr - EQ-KJ6300

Product Options

by Frequency:
KJ-6300 recirculating chiller provides a clean, reliable source of temperature-controlled fluid for both open tanks and closed-loop systems up to 75 L/min. It eliminates scale buildup, sewerage cost, and tap water cooling expenses. 
This recirculating chiller provides high cooling at a low cost and has a convenient digital reading and setting display. The standard magnetic drive centrifugal pump quietly produces high flow at moderate pressure. Positive displacement pump models provide less flow but have higher adjustable pressure for more demanding applications. The chiller has a temperature stability of ± 0.3°C and four wheels on the bottom for easy movement. The temperature range can be adjusted from 5 to 35°C. It is suitable for MTI CZ crystal growers, larger tube furnaces, high power induction heaters
