Partial Heat Recovery Kit: Turn Waste Into Warmth
Designed to make your system more intelligent and environmentally friendly, the Partial Heat Recovery Kit enables the recovery of 5–15% of the chiller’s nominal capacity. By harnessing waste heat from the cooling cycle, it reduces the need for additional heating sources—cutting natural gas usage and carbon emissions.
This approach aligns with industry best practices for heat recovery to improve energy performance, a widely recommended strategy for reducing operational energy demand in HVAC systems.
Included in the kit:
- Plate heat exchanger
- Piping assembly
- New front panel for easy integration
This solution is ideal for healthcare estates, residential developments, and commercial buildings seeking to reduce energy bills while maintaining optimal heating performance.

Inverter Pump Retrofit Kit: Drive Energy Efficiency
Pumping systems are often overlooked energy consumers. This kit introduces a dedicated inverter-driven pump, optimising flow rates to match system load in real time—leading to significant energy savings and more stable operation.
Available options:
- Low-head and high-head systems
- Integrated pump and inverter package
Compared to external solutions, this internal upgrade is more cost-effective and easier to install, ideal for NHS facilities, data centres, and university campuses where system efficiency and reliability are paramount.

Condenser Grille Kit: Safeguard Your Investment
External condensers are often exposed to debris, vandalism, and accidental impact. This simple yet effective grille retrofit helps protect the chiller’s vulnerable coil surfaces, thereby reducing maintenance costs and extending the unit's life.
Key benefits:
- Shields coils from physical damage
- Minimises cleaning frequency
- Improves long-term reliability
For industrial sites, pharmaceutical manufacturing, or urban installations, this kit provides peace of mind and reduces service callouts.
