Industrial & Commercial Super Low Noise Heat Pumps for retrofit, new build or process applications

The Pure Thermal team have been at the forefront of more specialist Industrial & Commercial Super Low Noise Heat Pump applications for over 15 years and remains committed to delivering the highest performing systems to meet the demands of each application.

Pure Thermal understand that Industrial and Commercial applications can call for Super Low Noise Heat Pump units that deliver both high performance levels and flexibility in application and this is reflected in the Industrial & Commercial Super Low Noise Heat Pump ranges that Pure Thermal offers.

Providing Super Low Noise Heat Pumps on a Supply & Commission/Maintain basis the Pure Thermal approach is application based with a committed approach to providing the best advice from the initial concept through to more detailed Heat Pump Selection & Specification discussions.

Super Low Noise Pumps

Pure Thermal Industrial Heat Pumps and Pure Thermal Commercial Heat Pumps are able to provide very low sound levels whilst operating with the Lowest Global Warming/Low Carbon Refrigeration Systems. Whether satisfying a retrofit application or a new project then Pure Thermal have a range of high specification Super Low Noise Heat Pumps to exceed the application demands.

Application flexibility is key to delivering both the lowest operating costs and also the highest levels of carbon savings. Pure Thermal Super Low Noise Heat Pumps are available in single stage (Monobloc) or Two Stage system configuration to match an applications requirement.

Monbloc Pure Thermal Commercial Super Low Noise Heat Pump units with single a stage refrigeration system are able to deliver a 70°C output temperature. This removes the need to specify a cascade or two stage (2 x heat pump) system for medium capacity applications.

Where waste heat is available a Pure Thermal Industrial Super Low Noise Heat Pump can operate with dual or multiple source configuration. This means that the unit will operate as a Super Low Noise Heat Pump but importantly also has the ability to operate with a second source to provide increased levels of efficiency.

R290 heat pumpFor example, an application may have a cooing requirement through the heating season, but varying in time and capacity, this means that a14°C flow is available from the chilled water return at certain times. Therefore if the external temperature is 7°C then the Pure Thermal Dual Source Heat Pump can operate using the 14°C cooling water return and not lower temperature air as its source heat which increases efficiency and hence uses less input electricity to operate.

Alternatively, Simultaneous 4 pipe Super Low Noise Heat Pumps can be provided by Pure Thermal for both retrofit and new projects.

Identifying the most appropriate system design is key to any project and to assist in this process Pure Thermal Super Low Noise Heat Pumps can be provided with a Heat Pump Ready Verification Service which identifies the most appropriate & available system options to deliver the highest level of efficiency. At this stage, the type of Heat Pump is secondary as the focus is on providing the best advice based on the opportunity that the application presents.

Contact The Pure Thermal Team for an initial discussion and you’ll find the best advice approach that’s geared completely towards matching the demands of your project with the most appropriate solution.


As the application of Heat Pumps becomes more widespread, the location and positioning of the heat pump unit can become more demanding. As the name of the Heat Pump suggests, this Heat Pump is designed to create as minimal noise as possible, to be installed in noise-sensitive locations.

With retrofit projects, there tends to be no obvious thought as to the future integration & location of the heating plant with fans/compressors, and the associated noise issues that result from an externally located plant.


With the above in mind, our Pure Low Noise Heat Pumps operate with market-leading, super-low noise levels and can be positioned in the most challenging noise-sensitive locations.

Secondary acoustic treatments and measures can be avoided with standard Pure Thermal Super Low Noise Heat Pumps.


  • City centres
  • Residential areas
  • Healthcare facilities
  • Other sensitive locations

These environments produce a range of opportunities for Pure Thermal Low Noise Heat Pumps, where noise pollution should be kept to a minimum.

Sound power levels of 65dB(A) can be achieved with location options driven by standard (out of the factory) acoustic designs.
