Daikin Applied (UK) has launched a new range of retrofit kits designed to improve the performance and energy efficiency of its R-32 Small Inverter Chiller (SIC) units. These kits aim to support facilities in reducing operational costs, improving system reliability, and advancing sustainability goals without replacing existing equipment.
The retrofit offering includes solutions for energy recovery, flow control, protection, and system monitoring. All kits are designed for easy installation, requiring minimal disruption.
One of the key solutions is the Partial Heat Recovery Kit, which enables the recovery of 5–15% of the chiller’s nominal capacity by capturing waste heat from the cooling process. The kit includes a plate heat exchanger, piping assembly, and a new front panel. This upgrade is suited to facilities looking to reduce natural gas consumption and carbon emissions.
The Inverter Pump Retrofit Kit introduces an inverter-driven pump to optimise flow rates based on system load. Available in low- and high-head options, this integrated package helps reduce energy use and stabilise operation, particularly in environments such as hospitals and data centres.
To protect outdoor installations, the Condenser Grille Kit provides a physical barrier for the unit’s coils. It reduces maintenance needs and helps prevent damage from debris, vandalism, or accidental impact—especially relevant for industrial or urban locations.
The Mobile App Connectivity Kit allows real-time system monitoring via Daikin’s mobile platform. This upgrade is targeted at multi-site operators and critical environments, offering remote performance tracking and faster maintenance response.
The R-32 Small Inverter Chiller range, available in both chiller (EWAT-CZ) and heat pump (EWYT-CZ) versions, uses R-32 refrigerant and offers a compact footprint, low sound levels, and an operating range from -20°C to 46°C. Capacities span from 16 to 90 kW (5 to 26 RT), making them suitable for a wide range of applications.
Daikin positions these retrofit kits as part of a broader effort to support the UK’s decarbonisation targets. With 80% of today’s buildings expected to still be in use by 2050, the company highlights retrofitting as a key strategy for meeting long-term energy and emissions goals.
