Production halls

The typical production hall problem

• Process heat gains push the hall past +35 °C in summer.
• In winter it is cold around the machines and draughty wherever the unit heaters blow.
• Dust and swarf clog filters fast.
• Overhead cranes leave no room for ceiling equipment in some of the bays.

Recommended models

Requirement	Model
Year-round climate	OXA K, OXA 530N/670N
Bays with overhead cranes	OXA SK, OXA SD
Make-up air for local extraction	OXA FD, OXA FK
Process humidity control	OXA HD, OXA HK

Worked example

A 3,200 m² hall, 9 m high, heat loss of 210 kW, with 90 kW of summer cooling required.

• OXA K-2 selected: 65 kW heating plus 34 kW cooling — 4 units.
• The two crane bays are covered by wall-mounted OXA SK-2 units instead.
• Automatic filter cleaning is set to run every shift because of the metalworking dust.

The investor’s view: a hall that never stops

In manufacturing, an hour of downtime usually costs more than a full day of installation work. So the decisive criterion for a heating system in a production building is not the price per kilowatt — it is whether it can be installed and serviced without stopping the lines.

• Installation without stopping production: units are hung zone by zone in available slots, with no main ducts crossing the hall.
• Stable processes: an even temperature field with no draughts means CNC tolerances hold, paint finishes properly and scrap rates fall.
• Zoning saves 8–15 %: the heat treatment area and the blank store do not need the same setpoint — each unit holds its own zone.
• Upgrade in pieces: replace the old air heaters bay by bay, without one large capital budget.

Case study

A steel fabrication plant, 3,200 m² and 9 m high: 4 × OXA K. The working zone now holds 24–26 °C through the summer and 18 °C in winter, with a 2 °C difference over the height. Complaints about draughts from the shop floor stopped.
