What are the most common types of spares for fan coil units?

Our range of FCU spares and replacement parts for fan coil components includes the items below. If you require a part that is not listed, contact our team, who may be able to offer bespoke service.

Condensate pump spares

The Sauermann Mini Pump S1-10 is a piston pump offers a distinctive ‘L’ shape that allows it to be used in new installations and as a replacement for most quick elbow pumps.

Fan motor spares

We offer a range of quiet-running centrifugal fans with forward-curved blades – supplied with a scroll housing and centrifugal fans with backward-curved blades that do not require a scroll housing.

Fan coil unit filter spares

Our standard filters are lightweight with a metal wireframe using EU3 media with 100% thermally bonded bicomponent polyester fibres calibrated to a particular thickness.

Other filter types are also available on request.

Fan coil unit control spares

Our range of spare fan coil unit controls includes a variety of fully programmable Native BAC net advanced application controllers:

Delta DAC-1180, 1180E, 1146 and 1146E FCU controls are suitable for medium input/output (I/O) requirements.
Delta eZNS T-100 network sensors offer intuitive user interaction
The intelligent R-ION communicating room controller offers full control customisation

Fan coil unit panel spares

We offer replacement metalwork and panels for most FCU models, including those from other manufacturers and systems that are no longer available. Options include:

Electrical box lids
Rear and filter access panels
Condensate pans
Main access panels
Spigots, blanking plates and other custom parts

Benefits of Ability fan coil unit spares

Different Ability spares for fan coil units bring different benefits to the HVAC system:

Condensate pumps

Versatility – the Sauermann Mini Pump can match a wide variety of system requirements with capacities up to 20kW and flow rates of up to 20 litres per hour. [28]
Acoustic design – low noise levels of 22dBA at full power for quiet operation.[13]

Fan motors

Efficient design – our compact centrifugal fans with external rotor motors have the motor positioned in the impeller for optimum cooling.
Energy saving – all Ability motors are available with EC technology, delivering energy savings and advanced control options compared with traditional AC motors.

Fan coil filters

Protect coils - fan coil filters prevent the build-up of dirt and dust on coils to help keep energy use under control, protect components and support healthy indoor air quality.
Reliable performance - our standard filters are designed, manufactured and calibrated to high quality standards for consistent long-term performance.

Fan coil unit controls

Improve overall FCU performance - the right controls can improve efficiency, reduce energy consumption and boost comfort.
Reduce energy use - Delta eZNS T-100 network sensors can pair with an application controller for advanced control strategies to reduce energy usage and optimise user comfort.
Enhanced customisation - the intelligent R-ION communicating room controller offers full control customisation for a variety of individual building products to allow more control flexibility.
Wide compatibility – Ability can provide control packages from other manufacturers, including pre-configured control FCU controls from Johnson Controls and Siemens to suit a wide variety of project scenarios.

Fan coil unit panels

Prolonged service life – the wide variety of FCU spares allow systems to be repaired or modified on site, helping to keep existing systems in service for longer.

Witness testing: Supporting the specification of Ability spares

At Ability by Dimplex, we carry out comprehensive testing of our fan coil unit spares at a dedicated facility in our factory in Poole, Dorset. We also offer witness testing, providing clients with complete transparency and confidence in the testing process and results relevant to their project.

Using the client’s drawings, we replicate ductwork layouts, grille locations and other system elements in our testing laboratory. By including FCU spares designed to upgrade an existing system such as condensate pumps, fan motors and controls the testing results enable specifiers and contractors to validate the benefits of carrying out upgrades and refurbishments. They can confirm the spares will comply with project requirements and fine-tune the fan coil system design.

FCU testing includes:

Acoustic testing: Confirms that sound levels meet specification, ensuring the acoustic performance of the installed fan coil units is as expected.
Volumetric performance testing: Verifies airflow, air resistance and pressure drops to streamline fan coil commissioning.
Thermal performance testing: Demonstrates heating and cooling outputs, fan coil performance and condensate management, ensuring the finished design delivers both comfort and efficiency.

All FCU testing is carried out using high-quality, regularly calibrated testing equipment. Once the fan coil unit spare parts testing is complete, clients receive a detailed report that includes test results, photographs, layout drawings and calibration certificates.
