Unichiller and Minichiller 

Simple to use, Huber chillers have small footprints, are robust, with modern energy management, fl exible functionality and modular
technology – these are the results of designs without compromise. Unichillers are intelligent chillers which can be used as an environmentally friendly and economic alternative to tap water for process cooling. Low temperatures increase effi ciency and recovery rates in gas condensation processes. In contrast to tap water a desired setpoint can be selected between -10/-20°C to +80°C and controlled with a temperature stability of ±0,5K. The product range includes 27 air cooled and 26 water cooled models, with cooling powers from 0,3kW to 50kW. Most models can be factory fi tted with a heater. The casings are made of high quality stainless steel to ensure long life.

Pump option

We offer alternative pumps for applications with higher pressure
drops. Further information on request.

Heating option

All units (except Minichiller with MPC) can be factory fitted with
optional heating and independent over-temperature protection.
Increasing the maximum working temperature to +100°C and
the temperature stability to ± 0,2 K. The new construction allows
constant operation in ambient temperatures up to +40°C. The
water-cooled models are especially quiet and require little cooling
water even at full cooling power. Despite the increasing costs of
water the ROI is exceptionally short. All models with maximum
pump pressure of 2,5 bar have an adjustable bypass and a pressure

Peter Huber Kältemaschinenbau was established in 1968 by Peter Huber as one of the first enterprises specialised in the development and construction of temperature control systems. They are technology leaders for high precision thermoregulation solutions in research and industry. Their products ensure precise temperature control in laboratories, pilot plants and production processes throughout the whole world – from -125 °C to +425 °C. Besides dynamic temperature control systems they develop and produce chillers as well as classic heating and cooling circulators. Typical applications can be found in the automotive industry, chemical and pharmaceutical industries, aerospace engineering and medical industry.
