The TLH-300 is a recirculating thermoelectric liquid chiller rated at 300W, or 1024 BTU/hr (@25°C liquid & ambient). The liquid temperature accuracy is precisely controlled to +/-0.1ºC based on a single configurable set point. The system also has heating capabilities to target temperatures above ambient.

TLH-300 has a unique dual reservoir design. The primary loop circulates coolant externally for the cooling/heating application, while the internal loop regulates the thermoelectric components. (Coolant is required in both reservoirs since they are not shared.)

Coolant flow rate, temperature, and reservoir level are monitored, and 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: 300W (1024BTU/hr) @ 25°C liquid/ambient
  • Temperature options: liquid set-point (+/-0.1ºC accuracy); toggle °C/°F
  • Pump: 10 manual levels, up to 8.5LPM (2.2 GPM)
  • Select only values you want displayed on the front 2-line OLED display (fixed or rotating)
  • Show liquid temperature, and two optional external K-type thermocouples
  • Show pump impeller speed in RPM
  • Show coolant flow rate in LPM/GPM
  • Show radiator fan speed in RPM
  • Adjust audio alarm and relay trigger (NO or NC) based on: temperature, flow rate, coolant level, pump RPM, and radiator fan RPM
  • Power input: 110/220VAC, 50-60Hz (NEMA 5-15 power cable included)
  • Maximum power consumption: 583W
  • Reservoir capacity: total 1.8 liters (0.8L external loop, 1L internal loop)
  • NPT 1/4in threads on back for fittings

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.
