Microgel – RCM-RCD – Flexible and Precise PRECISE COOLING WATER TEMPERATURE It supplies the temperature required (± 0.1°C /± 0.2 °F) by each process without thermal losses, delivering the chilled water close to the point of use, with complete independence from other processes. CONSTANT HIGH FLOW RATE THROUGH THE MOLD It supplies a constant high flow rate and pressure without pressure drops along the main pipelines, producing the pumping energy close to the point of use. Pumping energy consumption is 30 to 40% less than in Central Systems.

The Microgel® RCM-RCD water cooled chillers/TCUs are conceived for the control of process water of a single user. It is controlled by a microprocessor and fitted with a particular proportional control regulation valve which allows the set temperature to be kept perfectly precise and constant. The Microgel® units are designed to guarantee, adjust and constantly monitor a very high water flow to the mold. A turbulent flow means better heat exchange efficiency and a much more uniform temperature of the mold. This results in greatly reduced cooling time and much better part quality. An integrated automatic free-cooling system allows high energy savings to be achieved by exploiting the ambient temperature for cooling when possible. Two versions available:

RCD Double Zone Water Cooled Process Chiller Flow rate up to 76 m3/h (334 gallons/minute) Available with high pressure process pumps, too.

RCM - SINGLE ZONE - Offers the possibility of operating at constant temperature, flow and pressure; operating temperatures of minimum 0 °C (32 °F) and maximum + 90 °C (194 °F). RCD - DOUBLE ZONE – Harnesses the power of two Microgel® single zone RCM series machines in a single unit, saving a lot of space next to your process machine. This version is capable of automatically dividing the cooling capacity according to the thermal load of each zone in a completely independent way.

High Cooling Efficiency - Turbulent Flow - High flow rates High Heating Capacity - up to 48 kW High Reliability - Microprocessor sophisticated alarm system This line of Temperature Controllers is characterized by a very high flow rate, very high cooling capacity and excellent product precision at minimum energy costs. The hydraulic performance is the same as the rest of the Microgel® family. Two versions available: RBM - SINGLE ZONE - Offers the possibility of operating at constant temperature, flow and pressure; a real “booster” of the water circulating in the mold. Set point up to 90 °C (194 °F). RBD - DOUBLE ZONE – Encloses the potential of two Turbogel® single zone RBM series machines in a single unit, saving a lot of space next to your process machine. This version is capable of automatically keeping two zones of the mold at two completely independent temperatures, flows and pressures.

Flow rate up to 240 m3/h (over 1,000 gallons/minute) Available with high pressure process pumps, too.


Microgel® and Turbogel® are available for customized applications. Specific models have been designed for Extrusion and PET Preform Molding.

Microgel – RCX – Revolution in Cooling of Extruder

Microgel – RCP – High Performance in PET Preforms

The Microgel® RCX units are compact, water-cooled chillers, designed for cooling and/or temperature control of atmospheric pressure tanks in different industrial applications, mainly for plastic material extrusion.

The Microgel® RCP units are compact, water-cooled chillers, with high cooling capacity, that, thanks to their ability to supply high pressure and high flow rate to the process, are perfectly suited to cooling for injection molding of PET preforms and in general for packaging. With a shell-and-tube condenser, they can be utilized in existing plants with open type Cooling Towers.

Microgel – RAM-RAD – Plug-and-Cool

Two versions available: RAM - SINGLE ZONE RAD - DOUBLE ZONE

The Microgel® RAM and RAD units are compact, air-cooled chillers, with the same features as the RCM-RCD units. They are designed as a stand-alone machines: no need for connections to main water systems.

Lack of flexibility in temperature control. Variable water flow to molds, highly affected by the other users. Higher cooling cycle time due to high and variable delta T on molds. No possibility of communication with processing machines.

Running costs

Low reliability and high investment cost for a stand-by unit. High water pressure drops across the main water pipelines. Need to reheat water for molds requiring a higher temperature than the one provided by the central chiller. Need to keep the central chiller temperature set-point at the lowest temperature required by all molds. High refrigerant gas emission (high environmental impact) in case of leakage.


High costs for pipe insulation. Complicated and costly initial installation for centralized pump-tank groups. Complicated and costly expansions.



Possibility of searching and repeating the optimum cooling conditions for each mold. Complete independence of each setting. Precise automatic control of the mold temperature. Cooling conditions (temperature AND flow) permanently stable and under control for each mold. High cooling efficiency with low delta T of the process fluid through the mold, producing lower cycle times. A much higher quality of molded parts. Less scrap. Communication interfaces available with process machines.

Running costs

Total reliability, easy to replace with a spare unit in case of failure, minimum production downtime. Reduced pressure drops across the main water pipelines. High and constant flow often allows higher fluid temperature, reducing the risk of mold sweating and reducing energy consumption. Free-cooling opportunities as a standard feature. Little refrigerant gas emissions in case of leakage (minimum environmental impact).


Simple, quick and inexpensive installation. No need for intricate central pumping groups. No need for main pipe insulation. Modular concept is easy to expand.
