Process circulation chillers for industrial applications with cooling capacities up to 265 kW at working temperatures from -5 up to 25 °C in ambient conditions from -15 up to 50 °C

LAUDA Ultracool chillers provide reliable temperature control and ensure secure processing. The chillers of the UC series are available as Ultracool Standard (ST) and Ultracool Superplus (SP). All chillers are already equipped with an antifreeze protection thermostat to prevent freezing of the heat exchanger.

Integrated pressure switches protect the circuit against pressure levels that drift too high or too low. Housings made from galvanized steel and externally coated with epoxy resin protects against corrosion even under aggressive ambient conditions. Most of the models are suitable for outdoor installation. The Ultracool Standard units provide the necessary cooling capacity for customers who already have a pump and a water reservoir installed. The Superplus models are plug & operate systems equipped with a cold water tank, a centrifugal pump and an internal bypass

Ultracool UC Mini chillers up to 4.9 kW

The three UC Mini chillers are available with cooling outputs from 2.1 up to 4.9 kW. The models work with a hermetic compressor and a centrifugal pump. The pump is noise reduced and works with a very flat flow rate/pressure characteristic. This allows the user to easily adjust the water flow without jeopardizing the pressure.

Compared to the previous models the device dimensions were significantly reduced. Due to the optimized geometry of the devices an easy access to the components that need to be serviced regularly is provided. The temperature range in which the coolers can be used now covers an extended temperature from -15 to 50 °C ambient. Additionally outdoor installation of these circulation chillers is available as an option.

Options UC Mini

  • 5 bar pump
  • Refrifluid 1 (heat transfer liquid with antifreeze + bactericide + anticorrosive)
  • External bypass
  • Modbus remote control
  • Increased temperature stability ±1 K (instead of ±2 K)
  • Water-cooled version
  • Stainless steel housing
  • Feet
  • Customized color
  • Condenser air filter
  • 3-phase power supply
  • Outdoor installation (IP 54)

Ultracool UC Midi chillers up to 26.3 kW

Six UC Midi types have cooling capacities ranging from 7.1 up to 26.3 kW. The models work with a reciprocting or scroll compressor and a centrifugal pump. The noise-reduced pump allows customers to easily adjust the water flow. The use of R 134a as refrigerant ensures very low working pressures inside the refrigeration system and operation in ambient temperatures up to 50 °C . The intergrated motor fan speed regulator allows operation in ambient conditions up to -15 °C and reduces the noise level additionally.

The models UC-0060 to UC-0240 are also available as UC laser models with pre-configured options included.

Options UC Midi

  • 5 bar pump
  • Refrifluid 1 (heat transfer liquid with antifreeze + bactericide + anticorrosive)
  • External bypass
  • Modbus remote control
  • Auto filling kit
  • Increased temperature stability ± 0.7 K
  • Water pre-heater
  • Water-cooled version
  • Feet (wheels as standard)
  • External threaded BSP (British Standard Pipe) or NPT
  • stainless steel connections
  • Customized color
  • Condenser air filter

Options UC laser

  • 5 bar pump
  • Pump totally in stainless steel
  • Increased temperature stability ± 0.7 K

Ultracool UC Maxi chillers up to 265 kW

Within the Ultracool Maxi range, there are four chillers with cooling capacities from 34.1 up to 64.4 kW which work with one single refrigeration circuit. The five models from 87.9 up to 265 kW of cooling capacities work with two independent refrigeration circuits to provide a backup security. All Maxi models are equipped with scroll compressors, work with R 407C as refrigerant and are suitable for outdoor installation. The internal pipes for the water circuit are made of PP-R (polypropylene random copolymer) and are thermowelded. Besides the main advantage that these connections are absolutely leak free, PP-R is corrosion and frost proof, allow for smaller pressure drops and are long lasting.

The models UC-0300 to UC-0650 are also available as UC laser models with pre-configured options included.

Options UC Maxi

  • 5 bar pump
  • Refrifluid 1 (heat transfer liquid with antifreeze + bactericide + anticorrosive)

  • Water pre-heater
  • Water-cooled version
  • External threaded BSP or NPT stainless steel connections
  • Motor fan speed regulator
