GB142 Water Pressure Sensor

The revolutionary Fernox Total Filter TF1 is a unique hydrocyclonic and magnetic in-line filter that removes and contains magnetic and non-magnetic contaminants from central heating systems. Easy to install with no additional parts needed, the Total Filter TF1 has also been designed as a dosing point for the Fernox 'F' range of chemical water treatment products to ensure the system's long lasting performance.

The new Fernox TF1 in-line filter can be connected directly onto 22mm and 28mm pipe work using the valve fittings provided and can be positioned flush to a wall in existing pipe work. Once installed, it can be cleaned in seconds and easily and without having to disassemble or remove the unit.

"The Fernox TF1 has been specifically developed to provide installers with an easy to fit filter that helps maintain the performance and longevity of a central heating system," explained Francine Wickham, European Marketing Director. "The hydrocyclonic and magnetic filters remove and contain contaminants so that the system can work effectively. The Fernox TF1 filter then provides an easy way for installers to dose the system for long term protection."

All Fernox TF1 filters are manufactured in the UK and each one tested so installers can be assured of performance and reliability every time.

These differential pressure controls are for use as operating controls and/or indicating system functions through display lights or panels. They measure the difference in pressure exerted upon its two sensing elements. The controls are available for applications sensing air, oil or liquid. Typical applications are proof of flow across a chiller or water cooled condenser, proof of flow in a heating or cooling coil and lube oil pressure sensing on refrigeration compressors. On a proof of flow application the control measures pressure drop across two different points in either a closed water circulating system or a city water to supply system.

On a proof of flow application in a water chiller system the control activates a light or signal to indicate a loss of water.The control may also be applied as a lube oil pressure sensing control on refrigeration compressors. They may be used in combination with P28 and/or P45 oil pressure cutout controls on two compressor, single motor units to reduce the oil system cost. Special low pressure models are available for variable speed and screw compressor oil pressure applications.

Single and double pole models are available with contacts that open on a pressure differential increase or close on a pressure differential increase. Also available are models with single-pole, double-throw enclosed contacts or with main and separate reverse-acting auxiliary contacts. Controls with lockout feature require manual reset to reclose circuit after lockout. The ?trip-free? reset will not permit restart until reset button is pushed and released. The operation point of the control is readily adjusted by rotating the adjusting disk. The control set points are easily read on a calibrated scale.

Johnson Controls A19 Series temperature controls are designed to cover a broad range of uses for heating and general purpose requirements. Controls have SPST contacts which open on temperature increase or they may be supplied in single-pole, double-throw contact action. Various control ranges are available to cover working temperatures from -30 to 550° F (-34 to 288° C). Closed tank fittings and bulb wells are available for immersion applications. These controls are designed for open low and open high applications. Where critical or high value products are to be maintained within a specific temperature differential, a single control should not be applied to function as both an open low and open high control. In these applications, a separate backup control with alarm contacts should be wired to indicate when the back-up control operates.

In heating and air conditioning control systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. It also causes blockages in heat exchangers, heating elements and pipes, resulting in lower thermal efficiency within the system. The dirt separator separates off these impurities, which are mainly made up of particles of sand and rust, collecting them in a large collection chamber, from which they can be removed even while the system is in operation. This device is capable of efficiently removing the smallest particles, with low head loss.

Pro-Tek® 922 is a concentrated corrosion inhibitor treatment specially formulated for hot water closed loop heating systems. Many water sources used in hydronic heating systems can be very corrosive to metals when heated. Pro-Tek 922 will help to reduce corrosion on aluminum, brass, copper, iron, and stainless steel. Pro-Tek 922 has also been tested and is compatible with standard PEX and Onix tubing typically used in hydronic installations.

• Selectable temperature control – gives thermostat flexibility to control a range of heating systems and applications
• Comfort, economy and vacation presets – enable temperature changes at the touch of a button
• Pump protection – for hot water heating activates pump for one minute every 24 hours to prevent seizure Compact design – one of the smallest thermostats on the market
• Precise LCD – shows room temperature in increments of 0.1°C or 0.1°F
• Low battery indicator – gives 60 days warning to replace batteries
• Remote input – enables change of temperature modes by phone (telephone controller required)

The 132 series balancing valve accurately sets the flow rate of heating and cooling transfer fluid supplied to fan coils and terminal units or where flow balancing is required in solar thermal systems. Proper hydronic system balancing ensures that the system operates according to design specifications, providing satisfactory thermal comfort with low energy consumption. The flow meter is housed in a bypass circuit on the valve body and can be shut off during normal operation. The flow meter permits fast and easy circuit balancing without added differential pressure gauges and reference charts. The balancing valve is furnished with a preformed insulation shell to optimize thermal performance or both hot and cold water systems.
