Part No. LLX-7000 This product is archived and displayed for information only. It is no longer available for purchase. Released: 24 March 2017

Koolance's LLX-7000 is designed for heat loads up to 7000W where facility water or a chilled source is available. It contains a large stainless steel coolant reservoir and plate heat exchanger. The internal coolant pump outputs up to 9.1LPM (2.4GPM).

LLX-7000 monitors coolant flow rate, temperature, and reservoir level. A USB port is integrated for viewing and logging of temperature and sensor data using the Koolance System Monitor application.

Connections to the unit are made with Koolance QD4 and QD4H auto-shutoff quick disconnect fittings. Fittings for 13mm x 19mm (1/2in x 3/4in) tubing are included. NPT threads and other versions are available from Koolance.

Liquid Coolants

Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth. Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use silver with nickel in the same system.
