In distinction from the other control heads LOIP LT-300 has two-chamber pressure and suction pump that enables external open loop applications (i.e. an open remote vessel). This unit also can work with both water and non-aqueous fluids (silicon and other oils, glycol mixtures, etc.). The instruments are consisted of immersion thermostat-circulator LOIP LT-300 and a stainless steel baths with a gabled or flat lid. Product range of LT-300 family includes immersion thermostat-circulator without bath, and the models with tanks of volume 5 to 24 l.

Features and benefits:

Thermostats LOIP LT-300 include all the features of LT-100 and have in addition the following differences:
  • Powerful pressure-and-suction circulating pump provides temperature uniformity throughout a bath and a good heat
  • Heating element with an enlarged surface area and special heat dozing algorithm ensures safe heating of flammable fluids
  • Built-in cooling coil, when connected to tap water, permits operation at ambient or below ambient temperatures
  • Socket for an external Pt-100 sensor (option)
  • Adjustable high temperature protection via unrelated cut-out circuit (option)
