REVIEW OF THE YEAR condensing boilers. E The new model has been specifically

introduced with the needs of the contractor in mind, by including high quality components for long term durability, simple installation and maintenance, as well as an extremely competitive price point. The new boiler is available in three outputs

from 66kW to 130kW, with each version utilising stateoftheart design to produce a classleading unit. A robust stainless steel heat exchanger provides long term


LCO Heating Solutions has launched the new THISION® L ECO to bolster its light commercial range of wall mounted gas

performance and efficiency, while a flue non return valve, builtin modulating pump and onboard cascade controls ensure this new boiler is a practical fit for a wide range of commercial applications. The THISION® L ECO’s heat exchanger has a unique HEX geometry, combined with a flatbed burner, allowing it to operate at maximum efficiency while keeping NOx and CO emissions extremely low. For rapid servicing and maintenance, a specially designed internal configuration provides easy access to key components, as well as allow simple removal of the burner. Furthermore, a ‘TurnClick Logic’ ensures no

Mikrofill at Goodyers End Primary School, Warwickshire

oodyers End Primary School is a Community school that was established in 1996 following the

linking of Goodyers End First & Middle Schools. The school has a team of hardworking and committed staff who pull together to ensure that all the children receive a high quality of education. Under the umbrella of Warwickshire

County Council the decision was made to replace the existing LPHW heating plant at the school. The existing boilers and associated ancillaries were removed and replaced with new Mikrofill equipment by established Warwickshire term contractor Dodd Group Ltd. These included 3 No Ethos 90kW stainless steel condensing boilers each with an integral shunt pump providing a total modulation of 30 > 1 (270 > 9kW). Supplied with free standing support frames, Mikrovent 750 low loss header & air/dirt separator and a cascade header sensor, the new boilers supply VT

circuits around the Lower school area. The new LPHW installation was complimented with a Mikrofill 400 precommissioned pressurisation package. In addition the Upper School’s HWS supply

was further enhanced by the installation of a new Extreme 500 litre loading cylinder. The Extreme plate heat exchanger is designed to operate at a t of 30°C therefore optimising condensing boiler efficiency.

cooling units to produce the most compact, yet efficient Mini ECOi series ever. The new Mini ECOi VRF models, designed for residential and light commercial applications, deliver a powerful performance for properties with limited outdoor space and boasts significant energy savings, easy installation and high efficiency. The new Mini ECOi Series, which includes


4HP, 5HP and 6HP models, is the ideal solution for delivering highly efficient VRF technology to buildings with restricted external space, such as apartment blocks. Thanks to innovative new technology the

The technology that delivers this performance includes the new Panasonic Twin Rotary Compressor with wider inverter control for higher efficiency and improved partial load control. Moreover, the new bluefin heat

Unitrunk prepares for growth with systems accreditations

The TurboPOWER range,

Quality Assurance accreditation, along with OHSAS 18001 Health & Safety accreditation, following a year long process of preparation and audits. The certifications formalise systems that have been at the heart of Unitrunk’s business for many years, underpinning the company’s reputation for quality, customer service, environmental responsibility and safety. They will now support Unitrunk’s culture of continuous improvement through regular reviews and audits, enabling consistent best practice across the company.

C Explains Unitrunk’s operations director, Graham

Milligan: “The company’s major achievements in developing our business structure have made this the ideal time to merge our consistent best practices throughout Unitrunk. “These certifications will underpin customer

confidence in our systems and will also play an important part in succession planning for Unitrunk, ensuring all policies and processes are formalised and consistent to enable knowledge transfer from our health and safety, quality assurance and environmental managers to the whole team.” Unitrunk operates from six UK depots and the new

certifications are also intended to support consistency across all sites, with a centralised approach that is shareable across the business as it continues to grow. STULZ introduces the new range of air handling units

he totally redesigned AHU systems are available in eleven sizes from 30 kW to 520 kW.

The CyberHandler 2 series is used for air

conditioning everything from data centers to hotels, from commercial buildings to industrial sites.

As power densities increase, a new design

factor is coming to the fore  precision air conditioning solutions. Air handling units (AHU) incorporate all the air conditioning equipment of a data center in one outdoor container, therefore creating more space for productive IT systems inside the actual server

area. STULZ introduced its first air handling system back in 2015. With the CyberHandler 2, the specialist for reliable air conditioning solutions is now launching a comprehensively redesigned successor.

The CyberHandler 2 series includes eleven

output ratings from 30 to 520 kW. It combines free cooling, adiabatic cooling and mechanical chilling in one sealed outdoor container. The choice of chilling methods includes chilled water coils, scroll compressors or a redundant DX system with external condenser. If high availability is required, a fully weather independent air conditioning system with a

high level of redundancy can be designed, and can work in mixed mode for great energy efficiency.2/ New CPD highlights faster method of construction
