Technology
A process chiller has to hold the temperature even when the machine load changes within seconds. That is why MTA series include solutions that comfort chillers do not have.
The finned evaporator is immersed in the water tank. It allows high flow rates with low pressure drop, absorbs load peaks and tolerates contaminated process fluid.

The close temperature control version keeps the leaving temperature within a ±0.5 °C hysteresis – for lasers, measuring equipment and processes that cannot tolerate fluctuations.
TAEevo Tech (020–351) · TAEevo Tech MINI (M08–M10)
For glycol circuits, cold stores and wineries: leaving temperatures down to −10 °C in the standard series and down to −24 °C with TAEevo LWT.
TAEevo LWT · TAE G · TAEevo Tech · TWEevo Tech
Tank, piping and pump without ferrous materials keep the fluid clean. Essential for laser sources, pharmaceuticals and food, where rust or scale are not acceptable.
Option for TAEevo Tech and TAEevo Tech MINI
P3 or P5 pumps, twin stand-by pumps, internal bypass, automatic filling and operation in open or pressurised circuits up to 6 barg.

Free-cooling in practice
An example from the MTA catalogue: an FC TAE 161 module is added to an existing TAEevo Tech 161 chiller. Whenever it is colder outside than the process water, ambient air removes the heat.

Applications
The right process fluid temperature directly affects product quality, cycle time and machine life.
Cooling of moulds, injection moulding hydraulics, extrusion heads, rolls and thermoforming dies. Even temperatures mean fewer surface defects and shorter cycles.
CO₂, fibre and diode lasers need a stable temperature for a constant wavelength and beam quality. The non-ferrous circuit protects the source and optics.
Spindles, cutting oils and hydraulics. Precise cooling maintains dimensional accuracy, extends tool life and reduces scrap.
Dairies, breweries, bakeries, meat and vegetable processing. Direct or indirect glycol cooling and hygienic stainless steel versions.
Fermentation control, cooling of storage vats, must clarification and cold tartaric stabilisation below 0 °C.
Jacketed reactors, mixers, laboratories and solvents. Redundant refrigerant circuits and fast capacity adjustment when the process changes.
Cooling of technical gases, pre-treatment of biogas and natural gas, and dew point control of compressed air with a chiller and heat exchanger.
Heat treatment, welding machines, galvanic and coating baths and aluminium processing – a stable temperature for repeatable results.
KOMP-R + MTA
A chiller is only part of the system. KOMP-R takes care of the whole – with original parts and MTA factory support.
From your data (kW, temperatures, fluid, operation) we select the series and version, with free-cooling where it pays off.
Pumps, tanks, glycol, pipework and outdoor or indoor installation.
Setting up control, protections and supervision, and handover with operating instructions.
Regular inspections, condenser cleaning, leak checks and fast delivery of spare parts.
FAQ
From the process fluid flow and the temperature difference: Q = V × c × ΔT. For water c ≈ 4.19 kJ/(l·K), so 100 l/min cooled from 20 to 15 °C is about 35 kW. Add a 10–20 % margin. If you do not know the flow, we start from the machine data – for example the power of the hydraulic unit or the consumption of the laser.
When the required leaving temperature is below about +5 °C, or when the chiller and piping are outdoors in winter. 30 % ethylene glycol protects the circuit to about −15 °C, but it lowers the heat capacity of the fluid and the chiller capacity – we take this into account in the selection.
An air-cooled chiller rejects heat to the ambient air and is the simplest to install outdoors. A water-cooled one (TWEevo Tech, NEPTUNE G) suits sites with a cooling tower, well water or a heat recovery circuit – it is compact, quiet and suitable for indoor installation.
The tank absorbs fast load changes, so the compressor does not cycle too often and the temperature stays stable. In MTA units the evaporator is immersed in the tank, so it handles high flow rates and less clean process fluid.
Yes. MTA chillers work in open (atmospheric) or closed pressurised circuits up to 6 barg. The internal bypass protects the pump, and manual or automatic filling kits simplify the connection. Before quoting we check flows, pressure drops and water quality.
Often yes – especially with process water at 15 °C or more and year-round operation. When it is colder outside than the return water, the ambient air cools it while the compressors rest. In the example from the MTA catalogue the saving was 39 %; we calculate it for your location and operating hours.
