A new generation of air conditioning

All the comfort.
None of the outside.

One elegant indoor unit that cools, heats and dehumidifies — with no outdoor unit at all. The EHP monoblock rethinks air conditioning for the spaces of today.

Why switch

Split systems were designed for buildings that never move.

Modern spaces — mobile, modular, protected or simply beautiful — deserve a simpler answer. Here is what changes when the whole machine lives indoors.

No outdoor unit

The facade stays untouched. No brackets, no condenser boxes, no permits, no complaints from neighbours or authorities.

Installed in under an hour

Two openings in the wall, plug in, done. No refrigerant lines to connect, no certified gas handling, no crane or scaffolding.

One machine, every season

Cooling in summer, efficient heat-pump warmth in winter, dehumidification all year — plus an optional electric booster for the coldest days.

Made for compact spaces

A slim body only about 20 cm deep, designed to disappear into rooms where every centimetre counts.

No dripping, no drain worry

In cooling mode, condensate is re-evaporated and expelled automatically — no tank to empty, no visible drain pipe.

Moves when you move

The unit is factory-sealed and self-contained. Relocate it to another wall or another building without recharging or recommissioning.

Sustainability

Comfort that regulation — and the planet — already agree with.

The Global Warming Potential (GWP) of a refrigerant measures how much heat it traps in the atmosphere compared to CO₂. The difference is not small.

Legacy refrigerant (R410A)GWP 2 088
Common refrigerant (R32)GWP 675
EHP monoblock (R290)GWP 3
≈700× lower climate impact than R410A — and fully aligned with the EU's tightening F-gas regulations, protecting your investment for years to come.
1

Future-proof refrigerant

R290 is a natural refrigerant unaffected by the EU phase-down of fluorinated gases. No forced replacements ahead.

2

Inverter efficiency

The compressor modulates continuously instead of switching on and off, cutting consumption and keeping temperatures steady.

3

Heating at a quarter of the cost

With a COP of ~4, every kW of electricity becomes ~4 kW of heat — a fraction of the running cost of electric resistance heaters.

4

Independently verified

Performance tested by an accredited independent laboratory according to EU ecodesign and energy-labelling regulations.

Side by side

Monoblock vs. traditional split

The same comfort, delivered two very different ways.

Applications

Where the monoblock wins

Wherever an outdoor unit is impossible, unwanted or simply too much trouble.

Mobilhomes & modular living

Slim, light and self-contained — the natural fit for factory-fitted comfort in mobile and prefabricated homes.

Glamping & resorts

Silent comfort for premium hospitality, with nothing on the outside to spoil the view or the design.

Historic & protected buildings

Where facades cannot be altered and outdoor units are forbidden, the monoblock is often the only compliant option.

Offices & retail

Rapid deployment in rented or temporary spaces — installed today, moved tomorrow, no landlord negotiations.
