Air & water Cooled Chillers

TT-29800 WK

The TT-29800 WK chiller has a water cooled condensor and is designed for water temperatures from -25°C up to 25°C with water-glycol mixture.

  • Closed water-clycol circuit. The unit is equipped with a corrosion free water tank with a content of 150 litres. Once the water has cooled down to the required temperature, the compressor cuts out. It switches on again after the temperature has increased. The switch-on-point can be adjusted on the digital microprocessor controller. The circulation pump is running continuously. This unit is not suitable for water temperatures above  +25°C.
  • Automatic or manual refill
  • Long life expectancy due to the electronic control of operating time of the compressor.
  • All components are made of stainless steel or bronze
  • Castors

In 2018 Tool-Temp installed two TT430 Y units to a chemical company. These units were produced for the customer and are now listed as a machine in our product range. We flew the customer out to our head office in Switzerland to meet with the person in charge of the project, once they had all the requirements the machines went through to production. The units are equipped with three independent heat exchangers. The three-circuit cooling system makes it possible to work with oil below zero degrees. The installed self-optimizing temperature controller MP-988 works with three temperature probe inlets. The reference temperature for the regulation can be the temperature of the product inside the vessel or the oil temperature in the tank of the unit. To avoid any damage of the jacket, the pump pressure can be adjusted to the specifications of the vessel/reactor. The pump revolutions per minute can be adjusted very easily using the frequency inverter. As well as many other features.
