"The employees are satisfied. The air stratification is as promised. The air is distributed evenly. There are no cold or warm corners and no draughts."

Rudolf Kempter, Managing Director Mister Lady

The customer’s task

With the construction of its new logistics center, the clothing company Mister Lady faced the challenge of implementing a modern and climate-friendly hall heating system.
The system should

  • ensure a comfortable indoor climate without draughts,
  • work energy-efficiently and
  • focus on employee health.

In addition, the system had to withstand the intensive operating conditions of the warehouse with around 15 million parts moved and 3,600 trucks loaded or unloaded every year. A particular challenge was that the architect, general contractor and consultant had differing views on the heating system to be used.

The solution from LK Metall

After analyzing the requirements, LK Metallwaren was awarded the contract for planning and implementing the heating solution. Two RBW 125 warm air heaters with modulating Weishaupt gas blower burners were installed in each hall. The units draw in the rising warm air under the hall ceiling, filter it and return it to the room – with fresh air added or additional heating if required.

A stainless steel combustion chamber ensures durability and efficiency, while special air outlets and return air ceiling fans distribute the air evenly and draught-free throughout the room. The automatic PI differential temperature control with sensors at various heights ensures a constant temperature in the work area at all times.

16 heat exchangers exported to the USA and Mexico for use in drying processes

The result

The system impresses with its short response times, low operating costs and high level of convenience:

  • Average gas consumption: approx. 320 m³ per working day – less than € 100 operating costs per day
  • Overfulfillment of EnEV requirements
  • Comfortable room temperature without draughts or dust turbulence
  • Fast installation time: 1 week
  • Automatic adjustment to the time of day: Night cooling in summer through outside air intake

The warm air system ensures a stable, healthy indoor climate – in line with LK Metall’s guiding principle:
“For the sake of the climate.”
