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 fourpage brochure, showing the full range, is
available to download from the Unicrimp website

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, premix 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 gasfired 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 mediumsized, 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 fiveyear warranty against leakage. All other components are covered by a twoyear warranty. Both models are compact and
lightweight, and are designed for ease of

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:

available with frost protection and a comprehensive range of heating coils pre installed in insulated casings and matched flanges to fit directly onto the heat recovery units.
Versatile control options The factory fitted EcoPro 3 controller offers a plug and play capability and is ideal where standalone 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 EcoFault panel or BMS panel. Individually adjustable fan speeds on trickle and boost settings, with frost protection, automatic summer bypass 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 bypass and night time cooling options are standard. Full integration with BMS BAC net or Trend
systems for energy management and monitoring is available with filter monitoring via built in PDF switches. Additional ultralow energy summer trickle mode and a full space heating facility using a recirculation damper and LPHW coil are included in the programming. Optional colour touch screen

In addition to standard metering data, the meters can also measure volume weighted average flow temperatures (VWAFT) and volume weighted average return temperatures (VWART), as well as Coefficient of Performance (COP). Maximum power and flow readings are also recorded to help monitor peak loads.

(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 classbased 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 pressurewashing, industrial cleaning and surface defouling across all commercial and industrial sectors, including manufacturing, oil and marine industries and water utilities. John Jones, VicePresident 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 highquality 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.
