The best eco-friendly solution for HVAC / R
TKMicro microchannel solutions can bring several advantages which, in addition to having a positive impact on the environment, offer a high level of efficiency and ease of maintenance and cleaning.
RECYCLABLE MATERIALS
TKMicro uses 100% recyclable materials, in particular aluminum makes the components sustainable even at the end of their life.
GREEN REFRIGERANTS
Compared to traditional Tube and Fin technology, TKMicro saves 3⁄4 of the refrigerant charge, thus reducing both the global warming potential and the cost of charging. It is also compatible with the most popular green refrigerants: water, propane and ammonia.
LOW ACOUSTIC IMPACT
The geometry of TKMicro allows to drastically reduce the pressure drops leading, in addition to energy savings, also to the reduction of the acoustic impact , thus making these solutions particularly suitable for residential areas as well.

ThermoKey Know-how
ThermoKey is a leading company in the production of microchannel cores in Europe.
Thanks to 6 years of laboratory and field tests with different refrigerants, different surface treatments and in different working conditions, today ThermoKey can offer a solution designed specifically for the HVAC / R market.
TKMicro cores are used by leading European chiller / OEM manufacturers as well as installed by ThermoKey inside its own air-cooled units.
The state-of-the-art production process of TKMicro cores makes ThermoKey the ideal partner both for large-scale production and for smaller and more customized orders based on the customer’s specific needs.
The production line
ThermoKey has chosen the latest generation of Controlled Atmosphere Brazing (CAB) Furnace for the manufacturing of its aluminium heat exchangers.
The fully automated furnace is provided with an array of sensors distributed all over the line to guarantee control and stability of the brazing process.

TKMicro technology
MULTI PORT EXTRUDED (MPE)
TKMicro uses MPE tubes which allow the best heat transfer with small size. Three different types of MPE tubes are available to meet all the needs of our customers.
FIN
Thanks to the FEA (Finite Element Analysis) technique and the wind tunnel it has been possible to optimize the fin spacing and the number and angles of louvers in order to achieve minimum air side pressure drops and, at the same time, maximize the heat transfer.
The brazing process guarantees a perfect and permanent contact between tubes and fins.
Comparison: TKMicro vs round tube technology
In terms of performance TKMicro offers several advantages compared to a traditional tube and fin coil with the
same power.
Modular solution
TKMicro modular remote condensers and liquid coolers allow, by dividing the capacity into modules, to achieve the same total capacity of larger units. Thanks to its size and low weight the microchannel solution does not need special transport or high cube/open top containers, therefore it can also be installed in city centres where handling is often more difficult.
ADVANTAGES:
Up to 40% less installation costs
Reduction of total installation costs, crane renting and operations.
Up to 40% less load on the roof
Alluminium modules have a lower weight, resulting in less load on the roof (3.500 Kg-8 modules Vs 5.500 Kg-traditional unit).
Easy increase power when needed
In case it is necessary to vary the plant capacity, the modular system can easily adapt over time.
