Server-room and comms-room cooling for commercial offices, labs and FM contracts. ASHRAE-aligned, N+1 redundancy planning, up to a few tens of kW. Multi-circuit packs, BMS integration, refrigerant retrofit programmes. See the W4 case study for an example of recent work.
Gas Safe registered · 919290 F F-Gas / REFCOM Category 1 D Daikin Business Partner T TrustATrader Approved · Checkatrade listed Comms-room cooling design, heat load calculation, N+1 redundancy sizing, evaporator placement (typically in-row or ceiling-mounted), condenser routing (rooftop or external wall), refrigerant pipework, electrical isolation, BMS integration, controls and commissioning. Typical 5-day install for a single-room multi-circuit pack.
Inheriting a comms room from a previous contractor. Discovery visit, kit inventory, refrigerant log audit, BMS access check, written condition report. We pick up the PPM cycle or quote remediation work first if the kit needs catching up.
Comms rooms on R407C are common (still legal, quota-restricted). We plan retrofits to R448A across multiple circuits, sequenced to keep the room in spec throughout. See the W4 case study for a 3-unit, 6-circuit example.
Quarterly visits for mission-critical rooms. Each visit: condenser clean, evaporator inspection, refrigerant pressure log, control test (including failover where applicable), BMS data review, statutory F-Gas leak check on systems above the threshold. Written report and refrigerant log entry after every visit.
Anything from a single 7kW server cabinet up to multi-circuit rooms in the few tens of kW. We are not data-centre scale (5kW+/MW enterprise specialists own that lane), but for typical commercial comms rooms, lab cooling and MRI suites we cover the full range.
Yes. Comms-room cooling is mission-critical, so N+1 is the default unless the client explicitly wants a cheaper single-circuit. We design for one circuit holding the load while the other is in service or has failed, with automated failover via the BMS or a simple changeover controller.
We follow ASHRAE thermal guidelines (recommended envelope: 18-27°C inlet, max 90°F return). Air-management is usually done by the client's IT installer but we'll coordinate evaporator placement with the rack layout to support good airflow.
Yes. First visit is a discovery: kit inventory, refrigerant log audit, BMS access check, and a written condition report. From there we either pick up the PPM contract from where the previous contractor left off, or quote remediation work first if the kit has been neglected.
Quarterly visits for higher-criticality rooms. Each visit: condenser clean, evaporator inspection, refrigerant pressure log, control test (including failover where applicable), BMS data review. Plus statutory F-Gas leak check on systems above the threshold. Written report after every visit.
ASHRAE-aligned. N+1 redundancy. F-Gas certified. Multi-site FM contracts welcome.
