Down to earth solution from Unicrimp


nicrimp enters a brand new product category with the launch of a range of earthing rods and component products.


Earth Rods are conductive metal poles buried


directly into the ground and connected to the Earth circuit of an electrical installation. If there is a fault, they provide a low resistance path that allows electricity to safely dissipate out into the ground. An effective earthing system is a fundamental


requirement of any modern structure or system for both operational and safety reasons. Earth rods offer a simple, effective and reliable solution to ongoing concerns. The new Unicrimp Earthing Product range


comprises 10 products which together form an earthing system. At the heart of the system is the Threaded Earth Rod, made with a low carbon, high tensile steel core and molecular bonded 99.9% pure copper coating for maximum conductivity, strength and durability.


Where required, multiple Earth


Rods can be joined together using threaded couplers and the threaded driving stud attaches to the top of the Earth Rod to protect against damage when driving the Earth Rod into the ground. A selection of clamps and two inspection pits make up the range. A fourpage brochure, showing the full range, is


available to download from the Unicrimp website www.unicrimp.com/products/earthing For further information, contact Unicrimp on 01827 300600; email sales@unicrimp.com or visit:

innovative, energy efficient Classmaster® heat recovery ventilation units. Classmaster has been developed specifically


D


for classrooms and fully complies with the very latest BB101: ‘Ventilation, thermal comfort and indoor air quality 2018’ and BB93: ‘Acoustic designs for schools, performance standards (2015)’ guidelines. With nine chassis sizes and airflows ranging from 50 to 600 l/s, Classmaster delivers the very highest standards of air quality to meet every classroom requirement. Key features include a patented variable air mass flow heat exchanger, which maintains thermal efficiency at both 100% and 50% airflow levels by cleverly keeping turbulent velocity airflow across the heat exchanger. This is not possible with conventional heat exchangers as airflow goes into a laminar flow with no exchange of thermal energy. The unique configuration of the low


resistance heat exchangers, used in conjunction with 100,000 hour long life, low energy EC fans, delivers minimal sound levels and an impressive heat reclaim efficiency up to 89%. In line with the latest BB101 guidance


bulletin, Classmaster units have the option of ePM2.5 (F7) filters for inner city installations. With a low profile height of only 300mm, Classmaster can be installed within a ceiling void or surface mounted. A space heating option is


Both models in the EcoSable range are


fully condensing and have hot water recovery rates of 620 and 800 litres per hour, based on a temperature rise of 50degC. They each have a storage capacity of 186 litres. Key benefits of EcoSable water heaters


are their ability to operate at temperatures up to 85°C and with water pressures of up to eight bar.


The models are 92% and 93% efficient


and ‘A’ rated under the testing methodology used to assess compliance with the latest Energy Related Products regulations (ErP). Both use a low NOx, premix modulating gas burner, which closely matches output to demand, and a submerged combustion chamber with spiral flue that keeps the water heater in continuous condensing mode during hot water demand periods. EcoSable is the latest addition to


Lochinvar’s wide range of direct gasfired water heaters designed in line with the principle of low storage capacity and fast hot water recovery rates to provide a reliable and efficient supply of hot water. EcoSable models are particularly suitable for installation in large domestic and small to mediumsized, commercial hot water demand applications. Many specifiers prefer stainless steel


because of its longevity and ability to resist corrosion. The EcoSable storage vessel does not require cathodic protection and is covered by a fiveyear warranty against leakage. All other components are covered by a twoyear warranty. Both models are compact and

a variety of low carbon heat installations and features high performance PU foam, which makes it ideal for large district heating installations over long distances where minimising heat losses is critical. The lightweight pipe offers huge advantages over traditional steel pipework due to the speed and ease of installation. For more information visit:

Versatile control options The factory fitted EcoPro 3 controller offers a plug and play capability and is ideal where standalone control is required. Units can be activated either via volt free contact (VFC), from a time switch or BMS (enable / disable signal). The controller can give fault outputs either to the EcoFault panel or BMS panel. Individually adjustable fan speeds on trickle and boost settings, with frost protection, automatic summer bypass and night time cooling options are included as standard. Fans switch automatically to boost speed when CO2 is detected. The factory fitted Trend IQ422 Controllerm


offers individual and adjustable fan speeds on trickle and boost settings in all modes of operation. Frost protection, automatic summer bypass and night time cooling options are standard. Full integration with BMS BAC net or Trend

(WJA) has significantly updated its Safety Awareness course, a mandatory course designed to support safe water jetting in all applications. Central to the course upgrade has been the updating of 50 questions used to create six test papers for the classbased one day course, which is City & Guilds accredited and delivered across the UK and internationally. The WJA is the UK’s leading


provider of water jetting training for pressurewashing, industrial cleaning and surface defouling across all commercial and industrial sectors, including manufacturing, oil and marine industries and water utilities. John Jones, VicePresident of the WJA and Chairman of the


Training and Safety Committee, said: “We’ve taken account of feedback from trainees, training providers and our approved instructors. “The changes will give trainee


water jetting operatives and their employers confidence that their knowledge is being assessed consistently and they are receiving highquality training.” The pressures achieved by the


most basic pressure washing equipment are high enough to cause serious, and potentially fatal, injuries, warns the WJA, so it is essential that training is as effective as possible.
