ALH-2000 is an ambient liquid cooling system with heating capabilities to maintain a steady temperature for a non-constant heat load, or for a cold plate/sample which must stay near or above the ambient room temperature.

ALH-2000 monitors coolant flow rate, temperature, and reservoir level. It contains a large stainless steel coolant reservoir with an internal coolant pump outputting up to 8.8LPM (2.3GPM). A USB port allows control and logging of most features using the Koolance System Monitor application. A 0-5V differential voltage output is also provided for industrial process monitoring.

  • Cooling capacity: 2000W (6824BTU/hr) with 25°C liquid-ambient delta @ 8.8LPM
  • Heating capacity: 1000W
  • Temperature in °C/°F with set-point based on: liquid, or one of two optional K-type thermocouples
  • Pump: 10 manual levels, up to 8.8LPM (2.3GPM)
  • Select only values you want displayed on the front 2-line OLED display (fixed or rotating)
  • Show coolant flow rate in LPM/GPM
  • Show pump impeller speed in RPM
  • Enable audio alarm based on: temperature, flow rate, and/or reservoir coolant level
  • Enable relay trigger (NO or NC) based on: temperature, flow rate, and/or reservoir coolant level

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.
