Server Room Air Conditioning Leak Repair & Pressure Test in Nottingham

R410A Leak Detection & Emergency Coil Brazing

Location: Nottingham, Nottinghamshire

Emergency Server Room AC Repair in Nottingham
A commercial customer in Nottingham urgently contacted ACRC LTD after their critical server room wall-mounted A/C unit completely stopped cooling. Server rooms generate immense heat, and a failed cooling system can quickly lead to disastrous IT hardware failures. Upon attending the site, our engineers immediately diagnosed that the unit was short of refrigerant, indicating a leak in the system.

Safe R410A Recovery & Nitrogen Pressure Testing
To begin the repair, all remaining R410A refrigerant was safely removed from the unit and pumped into a dedicated reclaim cylinder to comply with F-Gas regulations. We then pressurized the system with high-pressure oxygen-free nitrogen. Both the indoor and outdoor units were completely stripped down to expose all leak-prone joints and pipework.

Pinpointing & Brazing the Coil Leak
Using specialist leak-detecting spray, we meticulously checked all joints and located a small leak on the outdoor condenser coil. Fortunately, it was in a repairable position. The nitrogen was safely evacuated, and our engineers used professional brazing gear to seal and repair the leak permanently.

Vacuuming, Recharging & Commissioning
Once the coil was brazed, we re-pressurized the system with nitrogen to rigorously test the newly repaired joint. After confirming it was 100% leak-tight, the system was put into a deep vacuum. We then recharged the unit with the reclaimed refrigerant, adding the precise additional charge required to replace what was lost. The system was powered back on, and the server room immediately began cooling safely again.

Save Money with Expert Fault Finding
A thorough pressure test and repair usually takes a day to complete, but it can save you thousands of pounds by avoiding the cost of a brand new installation.
