NEW PRODUCTS AIR COMPRESSOR
Upgrade delivers energy improvements CHILLER Low charge air-cooled ammonia chiller
The latest low charge air-cooled ammonia chiller from J&E HALL is designed to provide efficient cooling while minimising operating costs. It offers a range of cooling capacities, including cold storage (between -18°C and +15°C), process cooling (between -25°C and +7°C), and comfort cooling. The chiller features a straightforward mechanical design that facilitates servicing and maintenance. Key components are integrated into a user- friendly control panel, which includes a compact micro-controller, cloud-based monitoring, and a touchscreen interface. A refrigerant-cooled variable speed drive enhances efficiency. The condenser includes variable
speed-controlled fans to optimise operating conditions and reduce power
HEAT INTERFACE UNIT
Raising the level of HIU performance
The Flow 8500 is the latest indirect heat interface unit (HIU) from BOSCH COMMERCIAL & INDUSTRIAL. The new unit has been tested and registered under the BESA 2023 regime which has been introduced to help raise the bar for the performance of HIUs. The HIU delivers an improved domestic
hot water (DHW) response time and better volume weighted average return temperature (VWART). It also features new precision temperature sensors to ensure high performance, accurate control and network efficiency. Pete Mills, commercial & technical
operations manager, says: “The tougher targets of the BESA regime represent a real step forward for heat network efficiency. We are so proud to announce
EIBI | NOVEMBER � DECEMBER 2024 the successful registration of our
complete Flow 8500 HIU range.” ■

consumption, while low-noise fan profiles minimise sound levels during high-speed operation. An optional acoustic housing is available to further decrease noise and protect the equipment in low temperatures. Constructed with lightweight, robust stainless-steel pipework, the chiller is resistant to corrosion. It also features an ammonia leak detection system for constant monitoring. The HallScrew semi-hermetic
compressor, specifically designed for ammonia refrigerant, is central to the chiller’s operation. This design increases reliability and reduces maintenance needs, with minimal moving parts that lower the risk of
breakdowns. ■

With the launch of the new DX90-160 (RS) series, COMPAIR has extended its range of DX, oil-free rotary screw air compressors. They are said to offer up to 14% improvement in energy efficiency and up to 9% higher flow compared to industry standards. The range has been designed to offer best-in-class energy performance, excellent reliability and reduced lifecycle costs – in an oil-free compressor which is class zero certified according to ISO 8573-1:2010. This means there is virtually no risk of contamination in the production process, making it ideal for applications where high levels of air purity are essential. The new range includes
fixed and variable-speed models from 90 to 160kW, and includes 7.5, 8,5 and
10.5 bar pressure variants. Compressor rotor
surfaces can deteriorate over time, so the airend is protected with UltraCoat, an advanced rotor and housing protection process with excellent adhesion properties and temperature resistance. Maintenance has been considered at every stage
of the airend design. Its rugged bearing design eliminates the need for balancing pistons, helping to reduce complexity and service costs. Internal oil lines also eliminate the risk of leaks, while reducing the number of hoses and piping for simpler and
quicker maintenance. ■

MANIFOLD More efficient heat management
The Flexbox is a new manifold unit developed by ESBE, a Swedish company specialising in hydronic solutions, aimed at improving heat management in residential and commercial heating systems.
Designed for use in
systems with two or three heating zones, the Flexbox offers installers increased efficiency and flexibility when integrating boilers, underfloor heating or renewable heating sources, such as heat pumps. The unit can be
surface-mounted or recessed into a wall, with options for blanking strips and cover strips to enhance aesthetics. The Flexbox is intended
for DN20 compatability and there are two incoming connection ports (left and right) on the supply side, with one
plugged to streamline installation. It also allows for both insulated and uninsulated circulation units to be installed, along with shut off valves. Key components include a 3-way rotary mixing valve that allows for manual adjustments or the addition of actuators for automated
control. The design prioritises easy access to components for adjustments during commissioning and future maintenance, potentially reducing the need for follow-up visits. A quick-fit connection facilitates rapid detachment and
re-installation. ■
