Danfoss introduces EKE 100 Vertiv launches new coolant units
Danfoss is extending the expansion ecosystem . With stable performance , superior operating conditions , and six models to choose from , the EKE 100 range of superheat controllers and valve drivers supports highly reliable system functioning — encapsulating 20 + years of experience in superheat management . This new solution for superheat and valve drive control is easily integrated with other Danfoss products ensuring a simplified system design and implementation process . In addition to combining superheat management and valve driver modes in the same device , it
features the possible management of 1 or 2 valves independently plus variants with IP00 , IP20 , or IP20 with display . EKE 100 is based on more than 20 years of experience in developing best-in-class superheat management . Thanks to Danfoss ’ deep application knowledge in HVAC , food retail , and commercial refrigeration , this state-of-theart product range comes with user-friendly commissioning . So , whether for chillers , rooftop units , heat pumps , CRAC units , or cold rooms , the EKE 100 range works as a practical platform to help cooling professionals reduce development costs .
Vertiv has expanded its liquid cooling product portfolio with two new coolant distribution units ( CDUs ), designed to provide modular liquid cooling in data centers . The new CoolChip CDU systems can distribute coolant directly to liquid-cooled chips and reardoor heat exchangers enabling efficient thermal management for high-density computing environments . The CoolChip CDU 2300kW is a liquid-to-liquid system that offers 2.3 MW of cooling capacity , making it suitable for hyperscalers and colocation providers looking to deploy large-scale liquid cooling solutions at high densities . Vertiv claims the 2300kW has the industry ’ s highest CDU capacity per square foot , enabling data
centre operators to reduce cost and footprint by deploying fewer CDUs . The 350kW , meanwhile , is a liquidto-air system that offers direct-tochip liquid cooling via air-based heat rejection , enabling it to be retrofitted to existing facilities and provide liquid cooling for direct-to-chip applications without a facility chilled water system . Both of Vertiv ’ s new CoolChips can distribute coolant directly to liquidcooled chips and rear-door heat exchangers . The systems leverage unit-to-unit communication for system-level control , redundant power feeds , pumps , and filters for improved cooling availability , and integrated controls that enable operators to remotely monitor and manage them .
Fujitsu launches J-Series head pump mini VRF system
Fujitsu has launched the latest version of its J-Series heat pump mini VRF system , now operating on lower-GWP R32 refrigerant . A statement said that the AIRSTAGE J-VS is the result of two decades of development and multiple upgrades as this year marks the 20th anniversary of the product dubbed “ Little Napoleon ”. Aimed at small to medium-sized commercial applications or large residential spaces , the J-VS is available in capacities from 12-15kW . The single-fan chassis has a volume of 0.3m 3 , which is 17 % less than the previous model , and a weight of 74kg .
The statement added that up to 13 indoor units can be connected from a new range including compact 4-way cassettes , low static slim ducted , and high efficiency ducted units , alongside wall-mounted options . This line-up includes additional 1.7kW models and , due to heat exchanger optimisation , a new 1.1kW slim ducted unit . Compressor innovation improves seasonal efficiencies up to a possible 8.27 SEER , up to a 36 % increase from the previous model , and 5.37 SCOP , up to a 33 % increase from the previous model , it noted .
Showersave launches QB1-21XE WWHRS
Showersave , the award-winning manufacturer and distributor of waste water heat recovery systems ( WWHRS ), has unveiled the Showersave QB1-21XE , its latest innovation designed to help housebuilders improve energy efficiency and achieve Part L compliance . This new model builds on the success of its predecessor , the QB1-21 , and is designed to deliver maximum energy savings , compliance with building regulations , and ease of installation – key benefits for housebuilders and developers across the UK .
Designed to make the biggest impact on hot water energy savings for showers , the QB1-21XE is an affordable and effective solution for meeting Part L building regulations and future-proofing homes to comply with the upcoming Future Homes Standard ( FHS ). With its superior efficiency , the new system enables housebuilders to reduce energy consumption and lower homeowners ’ utility bills , while simultaneously supporting efforts to comply with the UK ’ s energy-saving targets .
