The CLient
Wilmot-Budgen Ltd, a corrugated cardboard and point-of-sale
display manufacturer based in Coulsdon, produces high-quality
retail displays for major UK brands.
Within the production facility, environmental conditions were highly variable, with seasonal extremes from hot summers to winter temperatures as low as -3°C. These fluctuations made it difficult to maintain consistent manufacturing conditions, directly impacting material behaviour and production performance.
“The results have been pretty outstanding in terms of the stability of the corrugated materials. Overall, we are very pleased with the results and the determination of Humidity Solutions to ensure that the system performs as promised.”
— Peter Burford, Director
The Challenge
The Solution
In response to these challenges, Humidity Solutions designed, installed, and commissioned the following solution to achieve a controlled production environment, as detailed below:
Humidification
Neptronic SKH
High Pressure Humidifier
High-pressure humidification system delivering precise RH control within 40–60% (50% ±10%RH), stabilising corrugated board and reducing static build-up
HEATING & COOLING
Vapac E-Heater & Cooling
via the SKH humidifier
Electric heaters installed to maintain internal temperatures of 18°C during winter (external lows to -3°C). Adiabatic cooling provided via humidification system during summer months.
AIR MOVEMENT & DISTRIBUTION
Vapac E-Heater & Cooling
via the SKH humidifier
High-pressure humidification
system delivering precise RH
control within 40–60% (50%
±10%RH), stabilising corrugated
board and reducing static build-up
AIR MOVEMENT & DISTRIBUTION
Vapac Destratification Fan
Destratification fans installed to recirculate warm air from ceiling level back to occupied zones, improving energy efficiency and maintaining consistent conditions at production level.
VENTILATION
Extractor fans installed above the false ceiling to remove excess heat and reduce heat transfer into the production area below
ENVIRONMENTAL CONTROL
Integrated control system maintaining stable temperature and humidity conditions within defined set points, preventing fluctuations where 1°C change can impact RH by 3%.
PERFORMANCE OUTCOME
A system designed to maintain conditions within the optimal
“quality gold zone,” improving material stability, reducing waste
and supporting consistent production performance.
