    High Temperature Heat Pumps from Pure Thermal

    The Pure Thermal team has been at the forefront of the Industrial & Commercial Heat Pump sector for over 15 years and remains committed to delivering the highest-performing systems to meet the demands of each application.

    Pure Thermal understands that Industrial and Commercial applications can call for High Temperature Heat Pumps solutions that deliver both high performance levels and flexibility in application, and this is reflected in the Five Industrial & Commercial High Temperature Heat Pump ranges that Pure Thermal offers. The overriding design advice from Pure Thermal is to reinforce the point that High Temperature Heat Pumps should be utilised only to operate at a high operating set point only when required in order to generate the highest efficiency levels possible for each particular application.

    Providing High Temperature 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. Pure Thermal Industrial and Commercial Heat Pumps are able to provide very high temperatures up to 120°C whilst operating with the Lowest Global Warming/Low Carbon Refrigeration Systems. Whether satisfying a retrofit application or a new project, then Pure Thermal has a range of high-specification High Temperature Heat Pumps to exceed the application demands from 30kW to 3000kW+.

    Application flexibility is key

    Application flexibility is key to delivering both the lowest operating costs and also the highest levels of carbon savings. Pure Thermal High Temperature Heat Pumps are available in single-stage (Monobloc) or two-stage system configurations to match an application’s requirements.

    Monobloc Pure Thermal Commercial High Temperature Heat Pump units with a single-stage refrigeration system are able to deliver an 80°C output temperature down to a -5°C external temperature. This removes the need to specify a cascade or two-stage (2 x heat pump) system for medium-capacity applications.

    For larger applications the Pure Thermal PLUS SO System delivers a Two Stage High Temperature Heat Pump option to 3000kW+ with single-system control & operation. With PLUS SO the control of the first stage High Temperature Heat Pump and the second stage water-to-water heat pump is completely self-contained to provide the next generation of large-capacity Two Stage High Temperature Heat Pump systems.

    Where waste heat is available, a Pure Thermal Industrial High Temperature Heat Pump can operate with a dual or multiple-source configuration. This means that the unit will operate as a High Temperature Heat Pump but importantly also has the ability to operate with a second source to provide increased levels of efficiency. For example, an application may have a cooling requirement through the heating season, but varying in time and capacity, this means that a 14°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 of heat, which increases efficiency and hence uses less input electricity to operate.

    Identifying the most appropriate system design is key to any project, and to assist in this process, Pure Thermal High Temperature 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.

    High Temperature Heat Pumps widen the scope for Heat Pump application and enable Carbon and Cost savings to be achieved across a wider range of projects and applications that would otherwise have utilised high-carbon fossil fuels.

    The typical barriers to the utilisation of heat pumps within an existing installation revolve around the heating system. Primarily the emitter refurbishment/replacement costs in order for the heating system to be able to operate at standard circa 45°C standard heat pump operating temperatures. In most cases, these refurbishment costs and the practical problems of modifying existing heating systems mean that 45°C or 55°C heat pump use is not possible.

    New Build Applications

    The typical barriers to the utilisation of heat pumps within a new installation revolve around the hot water production. Hot water production at 65°C is higher than standard heat pumps, which are unable to provide this output.
