Qvantum launches versatile QA50 air-to- water heat pump for residential and light commercial developments


S


wedish heat pump manufacturer, Qvantum, has launched a new 50kW air-to-water heat pump, the QA50, designed for multi-residential and light


commercial developments in the UK. Paired with the Qvantum QG water-to-water apartment heat pump, the QA50 enables a complete ambient loop solution for residential developments, delivering efficient, low- carbon heating, hot water, and cooling at both building and apartment level. As the UK market continues to demand low-carbon


heating solutions for residential developments, ambient heat loops are an increasingly attractive solution. Typically operating at low temperatures between 10°C and 30°C, they offer unparalleled efficiency, generating significantly lower heat losses than high-temperature networks while also acting like thermal batteries to optimise energy use during periods of low electricity prices. With a wide operating window, the QA50 is ideal


as the primary energy source for low-temperature ambient loop systems. Its compact dimensions and modular design allow multiple units to be combined, creating a scalable solution that can be tailored to project requirements. Its environmental impact is also minimised through the use of a natural refrigerant, R290. The QA50 is also effective as a standalone heating and cooling system for a wide range of light


commercial buildings, including offices, leisure facilities and mixed-use developments. In this setting, its modular design and scalable capacity make it a flexible, low-carbon solution, that doesn’t compromise on performance or occupant comfort. The QA50 operates with the QC PRO controller, providing centralised management of multi-unit systems


through a single intelligent platform. This enables housing providers and facilities managers to integrate and manage heating, cooling, hot water, and system components, simplifying system control, improving operational efficiency and performance, and providing visibility across the entire heating system. Jack Kerr, product manager, Qvantum UK, said: “Following the launch of the Qvantum QG earlier this


year, the addition of the QA50 enables any multi-occupancy building to benefit from a low-temperature network, without any loss of flexibility, performance, efficiency or apartment-level control.”

Thermoscreens launches CS Tower: a side-mounted air curtain built for the busiest cold store doors


hermoscreens, the UK air curtain manufacturer and part of Carver Group, has launched the CS Tower, a new air curtain for large cold store doorways in the cold chain


logistics sector. Unlike conventional air curtains mounted above a door, the


CS Tower stands beside the opening. The vertical format lets the unit run at a lower fan speed and means it can be installed and maintained while forklifts and pallet trucks keep moving through the doorway. The first model covers openings up to 4m high and 3m wide.


A costly problem at every door opening On a busy distribution site, a cold store door can open hundreds of times a day. Each opening lets warm, moist air into the room, adding load to the refrigeration plant, destabilising temperatures and forming ice on floors, a serious hazard where forklift trucks operate. Existing options fall short on large, high-traffic doors. Strip curtains are impractical where vehicles


pass through constantly. Rapid-roll doors open and close quickly but provide no separation while open. Dehumidification tempers incoming air rather than stopping it, is expensive to install and operate. The CS Tower creates a barrier of air across the opening, keeping warm air out at a fraction of cost.


Safety engineered in from the start At up to 80kg and up to 4m tall, stability is a priority with the CS Tower. The engineering team developed an accelerometer linked to the unit’s controls, which shuts it down if it ever begins to lose balance.
