The Challenge

Museums and heritage buildings rely on highly controlled environmental conditions to protect sensitive collections and maintain visitor comfort. Heating and cooling systems, often incorporating heat pumps and chillers, must operate safely, reliably, and in full compliance with regulatory and insurer requirements.

Over time, critical safety devices such as pressure relief valves and high-pressure switches can fall outside recommended service intervals, creating compliance risks and potential threats to system integrity. These components require specialist testing and, where necessary, replacement, all while ensuring minimal disruption to sensitive environments.

Why This Matters

Safety devices play a critical role in protecting HVAC systems, building occupants, and valuable collections. A failure in these components can lead to system shutdowns, refrigerant loss, or damage to plant.

By combining certified testing, compliant refrigerant handling, and targeted component replacement, we help museums and public sector estates maintain compliance, reduce risk, and extend the operational life of complex HVAC systems.

What We Deliver

Technical Scope:

• Testing and verification of high-pressure safety devices across heat pump and chiller systems

• Safe recovery and management of refrigerant prior to system intervention

• Replacement of pressure relief valves and associated safety components where required

• System evacuation, recharge, and full operational testing following works

Key Technical Activities:

• Pressure testing of high-pressure switches to confirm correct cut-out operation using calibrated equipment

• Controlled removal and replacement of safety-critical components

• Refrigerant recovery, storage, and reinstatement in line with F-Gas regulations

• System evacuation and recharge to ensure integrity and performance

• Post-works validation to confirm safe and correct system operation

• Delivery of works in sensitive environments with careful planning to avoid disruption

Results

✓ Compliance Assurance: Safety devices tested and aligned with regulatory and insurer requirements

✓ System Protection: Verified operation of critical safety components reduces risk of failure

✓ Asset Integrity Maintained: Refrigerant safely handled and systems returned to full operation

✓ Minimal Disruption: Works carefully planned and executed within operational museum environments

✓ Portfolio-Wide Application: Approach suitable for multiple plant types and locations across heritage estates
