Mycond OXA-GD — gas-fired warm air unit, 54.75 kW

Mycond OXA-GD is a ceiling gas-fired heating unit with top heat recovery. No boiler room, no distribution pipework: the gas line runs straight to the unit and the efficiency reaches 98.9%.

How the unit works

The burner fires a gas–air mixture and the heat passes through the exchanger. The axial fan draws the overheated air from under the roof — the air that would otherwise only warm the roof deck — and pushes it through the exchanger. After two pressure stages and silencers the warm air is delivered into the working zone.

That gives two effects at once: the heat trapped at high level comes back into the hall, and the losses through the roof drop. For sites without their own boiler plant it is the fastest route to a working heating system — no pipework, no pumps, no distribution losses.

Compared with a central boiler system

A classic water system releases its heat upwards, and the hot cushion under the roof is exactly where the energy escapes the building. The OXA-GD burns the gas directly above the working zone and drives the warm air down — so the same indoor temperature costs less fuel.

Wireless control and safety

What the controller actually adjusts

• Gas–air ratio — the burner modulates smoothly instead of cycling on and off at full load.
• Guide vane position — supply angle from a tight downward jet to a wide fan pattern.
• Fan speed — frequency control across the whole range.
• Wireless sensors — temperature read in the working zone, not at the unit.
• One terminal for the whole fleet — up to 1024 units within a 2 km radius.
• Safety — flame and draught supervision, gas shut-off valve, phase monitoring, overheat protection, safe shutdown with purge.

DWG drawings are available on request.

Where it is used

Assembly hall: units are hung along the span so the heat reaches the conveyor instead of the roof deck.

• production and storage complexes without a boiler plant;
• vehicle workshops, service stations and showrooms;
• agricultural buildings and hangars;
• sites that need heating running quickly;
• leased premises where a water circuit is not an option.

Frequently asked questions about the Mycond OXA-GD

Is a boiler room needed?

No. The unit runs directly on gas: a DN20 gas connection, a DN80 flue and a 380 V supply are all it takes.

How much gas does it use?

About 5.21 m³/h at full output; at part load the consumption falls proportionally thanks to the modulating burner.

Can several units be combined?

Yes — up to 1024 units can be grouped into zones and controlled from a single terminal.

Is design approval required?

Yes — the gas connection and the flue are executed to a design by a licensed company; we provide the technical data needed for it.
