OUR TRENCH HEATER SYSTEM ILLUSTRATION GLAZED WALL DOWN DRAUGHT (air cooled by contact with exterior window) Trench heater with fan HEATED AIR MIXES WITH DOWN DRAUGHT (positioned within floor) ROOM AIR DRAWN INTO LTHW CONNECTIONS Our trench heaters are designed to provide thermal comfort in spaces with large external glass walls. To do this a thermal screen is created in front of a glazed surface, which separates the cold surface from the indoor environment. At the same time air flow prevents condensation of air humidity on the surface. The unit is available with a fan assisted heater or stand alone using natural convection to circulate the air heated by the water based heat exchange. PTHF ACOUSTICS It is necessary to take into account the acoustic characteristics of the trench heater and the environment in which it will be used. The recommended upper limit for a day use room is 40 db(a), the limit for a night use or relaxation room is lowered to 30 db(a), the limit for offices is 50 db(a). INTEGRATED CONTROLS To ensure comfortable and economical operation with a low noise level our fan assisted trench heaters are controlled with a digital thermostat that can be incorporated into building management systems (BMS). The low volume of water in the heat exchangers secures fast warming to operating temperature. COUNTERACTING DOWN DRAUGHTS & CONDENSATION APPLICATIONS Our Trench Heaters are designed for use in office buildings, commercial centres and public spaces. They are also suited to domestic use for heating living rooms, corridors, halls and conservatories. BESPOKE SOLUTIONS To accommodate the variety of modern building designs, we supply both angled and curved trench heaters that can continuously follow the running line of a glass wall. 2 www.pricetwa.co.uk +44 (0)1934 835900 S
DELIVERING INDUSTRY EXPERTISE Price TWA was formed in 2008 from the merger of two leading heating and ventilation suppliers in the UK, Price Technical Ltd (Formed in 1997 to supply high quality ventilation and heating systems) and TWA Panels UK Ltd (formed in 2003 to supply radiant heating panels). Together we now offer one of the widest ranges of heating and ventilation solutions in the UK. We are recognised in the industry not only for excellent design and manufacture of heating and ventilation systems but also for maintaining strong relationships with both specifiers and contractors. This combined with our strong manufacturing background has set us among the very best of the UK s heating and ventilation solutions providers. OUR EXPERIENCE We have grown and adapted as the construction industry has, offering modern solutions to modern issues. We understand that every project has individual needs and always offer flexible informed solutions to meet the needs of every project. Years of experience and industry expertise will provide you with a solution that s cost effective, efficient and suited to your building s individual design and function. Within this brochure we cover our wide range of trench heater systems. If you require alternative ventilation solutions please refer to our Product Solutions brochure. We operate from our manufacturing base in Bristol where we create and distribute our products. We have a dedicated team of sales engineers and representatives throughout the UK and Ireland offering exceptional customer service.

OUR CONTROLS & OPTIONS FAN ASSISTED & NATURAL CONVECTION THERMOSTATS RTD201 FAN ASSISTED FAN ASSISTED CONTROL FUNCTIONS Z-RT001 NATURAL CON. CONTROLS Controls and a power supply are required for trench heaters to secure their correct function. The temperature in the room is assessed by a room thermostat which controls the fan. The flow of heating through the heat exchanger is controlled via an electrothermal actuator. The entire circuit functions on the basis of safe voltage of 24 V DC. PROGRAMMABLE 7 DAY TIMER CONTINUOUS FAN CONTROL THREE OPERATING MODES INCLUDED IN THE RTD201 DIGITAL THERMOSTAT INDEPENDENT TEMPERATURE CONTROL HEAT MEDIUM TEMPERATURE SENSOR REMOTE CONTROL OPEN WINDOW SENSOR CONTROL EXTRAS Natural Convection controls do not have any of these functions but do not require a power supply. ANGLE/CURVE ALTERNATIVES ANGLED S & GRILLES To accommodate the variety of modern building designs, we supply both angled and curved trench heaters that can continuously follow the running line of a glass wall. Our trench heaters are designed to be connected together so multiple units can span the perimeter of a space. CURVED EXAMPLES Low transverse (90º Aluminium only) Transverse roll-up (from 40º to 320º) Linear (from 40º to 320º) Inward arc ANGLE EXAMPLES Inside turn Outside turn Acute turn Double arc 4 www.pricetwa.co.uk +44 (0)1934 835900 S
