Clade Announces New Commercial R290 Heat Pumps for U.K. Market

The OEM said the units are designed to meet the market’s preference for lower capital costs, a compact footprint and easy installation.

U.K.-based OEM Clade Engineering Systems has announced the expansion of its portfolio of propane (R290) heat pumps with the introduction of its new Rowan lineup and the expansion of its Birch range for commercial applications.

Clade has also announced the launch of the Maple, a new line of commercial CO2 (R744) heat pumps for space heating and hot water production. Tim Rook, Clade’s Chief Marketing Officer, told Hydrocarbons21.com that the new products have been developed to meet the needs of the U.K. market.

“The U.K. market seems to favor lower capital cost rather than optimum efficiency,” said Rook. “Space is also frequently an issue, and [our heat pumps] are built for easy [installation] by contractors who are not familiar with this new technology.”

Expanding R290 portfolio

Clade’s new R290 heat pump range, Rowan, will consist of four models with heating capacities of 150–375kW (42.7–106.6TR) at an ambient temperature of −5°C (23°F). The units can provide heating and hot water up to temperatures of 65°C (149°F), which Clade says makes it well suited for a variety of commercial applications.

“Each model in this lineup is engineered to deliver exceptional performance without sacrificing space or breaking the budget. Perfect for businesses looking to maximize efficiency and value!” says Clade in the Rowan product brochure.

The heat pumps include compressors from Italian manufacturer Dorin and controls from Siemens, the latter of which allow for full connectivity, performance monitoring and grid flexibility, according to Clade.

The first Rowan heat pump will be ready for delivery by the end of 2024, added Rook.

For smaller-capacity applications, Clade is expanding its Birch range of R290-based heat pumps. A new 75kW (21.3TR) model will be added to the lineup to close the gap between its existing 50kW (14.2TR) unit and the new Rowan heat pumps. The 75kW Birch heat pump will be available later this year, he added.

High-temperature heat pumps

In addition to its new R290 products, Clade has launched a new range of CO2 heat pumps to complement its existing R744 portfolio.

According to the manufacturer, its new Maple range can deliver temperatures up to 80°C (176°F), which is likely to meet the needs of “most buildings.” Unlike the majority of CO2 heat pumps currently on the market, Clade’s R744 units are able to provide both space heating and hot water production due to their ability to accept a higher return temperature.

The range consists of four models that cover heating capacities of 200–500kW (56.9–142.2TR) at ambient temperatures of −5°C. Sitting between Clade’s Acer and Oak CO2 heat pumps, Maple is a cost effective, low-carbon and compact option for end users, the company said.

B Corp certification

In recognition of its commitments to sustainability, Clade recently received B Corporation certification from B Lab, a nonprofit organization that says it is working to transform the global economy.

“B Corp Certification is a designation that a business is meeting high standards of verified performance, accountability and transparency on factors from employee benefits and charitable giving to supply chain practices and input materials,” B Lab explains on its website.

To be classified as a B Corp, a business must score at least 80 points on the B Impact Assessment. According to Clade, it scored 86.

“The Board of Clade is immensely proud to announce its achievement of B Corp certification, a significant milestone that underscores our unwavering commitment to not only financial success but also to social and environmental responsibility,” says Dean Frost, CEO of Clade, on the B Corp page on the company’s website. “This is not just an accolade; it is a call to action, a commitment to continuous improvement, and a significant step towards our vision of creating lasting, positive change in the world.”

With regard to the environmental aspect of the assessment, Clade received 37.9 out of a possible 45 points, which it says reflects its efforts to reduce its own greenhouse gas emissions as well as those of its customers thanks to its natural refrigerant-based heat pumps and refrigeration systems.
