NEW PRODUCTS REFRIGERANT GAS DETECTOR


Leak detection system improves occupant safety


AQUILAR has launched a new refrigerant gas detection system aimed at improving safety and sustainability in air conditioning installations. The system is designed for both new and existing buildings, including commercial and residential spaces such as hotels, apartments, hospital rooms and offices. The refrigerant gas detectors


effectively identify leaks within occupied areas, helping to protect occupants and reduce potential environmental harm. They can function as standalone units or be networked together for centralised monitoring in larger buildings. This new sensor technology is based


on Molecular Property Spectrometry, which offers a lifespan of 15 years for the sensor head without requiring calibration. This longevity is a notable improvement


VENTILATION


MVHR system with intelligent cooling tackles overheating


over traditional semiconductor sensors, which typically last up to five years. These sensors are also immune to false alarms from other non-target gases such as hairspray or deodorant used in hotel rooms and apartments. Installing a fixed refrigerant gas leak


detection system can lead to reduced ownership costs, lower environmental impact, and enhanced safety for occupants, making it a practical option


for building management. ■ www.rehau.com


both heat pump and heat recovery capabilities, and is available in two models: the standard air365 Max and the high energy efficient air365 Max Pro. The systems are compatible with over 64 Set Free indoor units, offering versatility for various installation types. The systems feature SmoothDrive


AIR CONDITIONING


VRF offers tailored cooling and heating


JOHNSON CONTROLS�HITACHI AIR CONDITIONING has launched the air365 Max, a new top-flow variable refrigerant flow (VRF) air conditioning system. The air365 Max is an end-to-end VRF solution that aims to deliver seamless comfort, energy efficiency, and easy installation and maintenance for HVAC professionals, design consultants and commercial building owners. The air365 Max series comes with

2.0 technology to operate at stable and precise temperatures that provides greater comfort for building occupants. When combined with other smart features such as Gentle Cool and Warm Feet, air365 Max addresses the issue of cold or hot air drafts and further improves the users’ comfort level. Both the air365 Max and air365


Max Pro produce a Seasonal Energy Efficiency Ratio (SEER) of up to 7.35 and 8.38 as well as a Seasonal Coefficient of Performance (SCOP) of up to 4.76 and 5.19 respectively. To support HVAC professionals, the


company also offers the airCloud Tap app, CSNET Manager controller, and airCloud Pro cloud-based controller, providing tools to optimise installation,


operation, and maintenance. ■ www.hitachi-hvac.co.uk


black exterior, allowing it to blend seamlessly into various commercial environments, such as shops, offices and hotels. It utilises Bluetooth technology for easy connectivity with smartphones through the M-Air Pro app, which offers three operational modes: user, administrator, and service. This app supports a wide range of functions, from basic control to advanced data management. User-friendly operation is


facilitated by five touch buttons and a clear display, along with intuitive pictograms. To streamline installation, configuration data can be exported


New from VENT�AXIA is the Lo-Carbon Sentinel Econiq Cool-Flow, a mechanical ventilation with heat recovery (MVHR) system combined with an intelligent cooling module. It is designed to help housebuilders address the issue of overheating in new, airtight homes. The Lo-Carbon Sentinel Econiq


Cool-Flow utilises R32 refrigerant to provide powerful cooling, lowering fresh air supply temperature by up to 21°C. It boasts an Energy Efficiency Ratio (EER) of up to 4.12 and best-in- class Specific Fan Powers (SFPs) and thermal efficiencies up to 93%. The system features intelligent controls that automatically manage heat recovery, summer bypass, and active cooling to maintain comfort efficiently. In the cooler months, the system can provide up to 93% heat recovery


MODBUS MODULES


Enhancing building automation solutions New from SIEMENS is the Desigo


Essentials Modbus I/O modules, designed to enhance the existing TXM Module range. These modules are compatible with any Modbus controller, including the Connect Box and PXC4/5/7 automation controllers. Integration is straightforward via the ABT software, connecting directly to the Modbus ports of Siemens PXC controllers.


There are three module


variants available – EM1.8D: 8 digital inputs; EM1.8R: 8 relay outputs with no contacts; and EM1.8U: 8 universal inputs/outputs (resistive and analogue inputs/outputs or digital inputs,


to minimise heating costs. In warmer months, the intelligent 100% summer bypass and active cooling module can be used to prevent overheating, providing up to 3.78kW of cooling. The filter options remove allergens


and particulate matter. They also maintain the system’s energy efficiency, reduce heating and cooling costs, and


enhance longevity of the system. ■ www.vent-axia.com


configurable). Though they maintain the look and feel of the existing modules, they are smaller and easy to configure, with no software required to setup. They also offer the potential for cost efficiencies, enabling connections with


datapoints to be made more easily, a particular advantage in more remote areas of a building. They require a 24V AC or DC supply.


They can also be used in conjunction with Desigo Optic, a BMS platform


specifically designed to offer an open, powerful and scalable software solution


for one to many buildings of any size. ■ www.siemens.co.uk


to smartphones, simplifying setup for multiple units. In case of errors, operational data can be saved for analysis, improving maintenance efficiency. The RC-ES1 includes a function to


monitor power consumption for each operation mode, helping users optimise energy usage. The M-Air Pro app allows for the


automatic and continuous transmission of settings to up to 20 remote control units within the Bluetooth connection range. This capability significantly


enhances convenience and efficiency. ■ www.mhiae.com
