Overview

“COOLING ONLY’ and “HEAT PUMP”
In the Same Model

The Withair® DC Inverter Through Wall Packaged Air Source Heat Pump can operate both for summer air conditioning and, in heat pump mode, for winter heating. All, in the same model, with maximum simplicity of installation. it is the ideal solution for most living contexts and for the most common domestic needs. Simplicity at your fingertips.

As with all heat pumps, heating performance decreases as the outside temperature falls. Often the need is for a product that maintains sufficient performance even at very low external temperatures. The heat pump is integrated (and not replaced) by a 1kW backup electric heater that intervenes automatically for very low outside temperatures or to heat very cold rooms quickly. For this reason, heat pump can ensure a heating power of over 3kW even at -7°C with an additional electrical absorption of 1kW compatible with the electrical power available in homes. Heat pump thus becomes a true complete heating system even in particularly cold climates.
Optimised Power, Reduced Consumption

With DC Inverter technology, the powers are optimised for maximum comfort with less consumption and noise, and thanks to Dual Power you can use maximum power to reach the required temperature in the shortest possible time. Once reached, the unit automatically adjusts itself in function of comfort. The external grilles are foldable: they open when the machine is running and close when it is switched off, so as to minimise dust, noise and pollution, maximising comfort.
Noiseless and Space-saving

Almost invisible, powerful, noiseless and space-saving: this is the Withair® air conditioner without an external unit. No more of the usual bulky, unsightly condensing units that spoil homes. Withair® has developed a high-efficiency solution with a hyper-compact design that minimises aesthetic impact. Just 16 centimetres deep, super simple installation and DC Inverter technology to optimise performance.
Maximum Versatility to Meet Every Need

High on the wall or down on the floor? Withair® can count on a complete product range that allows you to find the right model for every type of installation. All you need is an external wall and you can find the space to insert it high up on the wall, low down on the floor, in the corner or to the side of a French door.
Built-in Reliability

Keeping in mind that productivity only occurs when equipment is operational, Withair® has taken the steps to ensure that packaged system is up and running. Early indicators such as phase/reversal monitors and loss of charge protection provide diagnostics which prevent failure.

Heat pump has a 100% metal body that is strong and robust. In the design, the dimensions of the components have been reduced and optimised to include all the functions required for perfect operation within a hyper-compact design. The minimum depth, the right colour, the perfectly smooth surface, the body made entirely of metal, a product designed to integrate perfectly into any domestic environment, giving excellent performance.
Easy to Install and Service

Small footprints and low weights combined with factory installed components like pipes, etc., reduce installation time and cost. Colored connectors and wiring, as well as factory-tested units make packaged system the right choice.

Form follows function, Hyper-compact design and no plastic. The minimum depth, the right colour, the perfectly smooth surface, the body made entirely of metal... a product designed to integrate perfectly into any domestic environment, giving excellent performance and at the same time... disappearing... in both horizontal and vertical developments, the design of unit has been carefully studied down to the smallest detail so as to combine form and function in a perfect symbiosis. Unit has a 100% metal body that is strong and robust. In the design, the dimensions of the components have been reduced and optimised to include all the functions required for perfect operation within a hyper-compact design. The depth? Just 16 centimetres. An ultra-thin thickness that minimises aesthetic impact, both inside and out.
Consistent Comfort

Withair® Packaged DX System (All-in-one DC Inverter Air conditioner) is designed to keep your building comfortable at any temperature and at all design conditions.

The Withair® Through Wall Packaged Heat Pump provides adequate dehumidification at full load conditions, so building occupants can experience a more comfortable environment throughout the day.
Rigorous Testing

Our units are rigorously rain tested to ensure water integrity. Actual shipping tests are performed to determine packaging requirements. Units are test shipped all over the world to determine the best packaging. Factory shake and drop tests are used as part of the package design process to help assure that the unit arrives at the job site in top condition. Rigging tests include lifting a unit into the air and letting it drop one foot, assuring that the lifting lugs and rails hold up under stress. A 100% coil leak test is performed at the factory. The condenser coils are leak tested at 660 psig and evaporators to 450 psig.

All parts are inspected at the point of final assembly. Sub-standard parts are identified and rejected immediately. Every unit receives a 100% unit run test before leaving the production line to ensure it lives up to rigorous Withair® requirements.
