Water conservation isn't a novel concept, but emerging forces are creating renewed attention among commercial property owners. With the prospect of water resources drying up, facility executives and home owners must find new ways to conserve water. Autotaps have introduce ATT-1103 for residential use, the battery-powered tap features an infrared sensor and manually control.
A Thermostatic Mixing Valve is a device that mix or blends hot water (usually stored at temperatures high enough to kill bacteria) with cold water to ensure constant, safe outlet temperatures preventing scalding.
How a thermostat works:Hot and cold water entering the valve is mixed to a temperature pre-selected by the user or installer. A thermal-sensitive mechanism within the valve’s body automatically proportions the amount of hot and cold water entering to produce the required blend.
The mechanism then automatically compensates for any reasonable variations in supply pressures or temperatures within the design range to maintain the pre-selected temperature. In the event of cold water supply failure, the thermostatic mixing mechanism will automatically shut down the flow to prevent discharge of dangerously hot water.
The flow will also be shut down in the event of a hot water supply failure to prevent thermal shock. In the event of a sudden supply temperature increase (‘spike’), the TMV will quickly (but not absolutely instantly) adapt and deliver water at a safe temperature.
Thermostatic mixing element:There’s a temperature sensitive element which expands or contracts depending on the temperature of the water surrounding it. When the thermostatic element senses a temperature change, it moves a piston which changes the proportion of hot and cold water being mixed in the valve. This movement enables the valve to remain stable and to shut down in case of cold or hot water failure.
Piston Component:Usually connected to the thermostatic element, the piston moves back and forth over the cold and hot ports of the valve, changing the proportion of hot and cold water entering the valve depending on the temperature of the water.
Return spring:When the thermostatic element expands it moves the piston under its own energy and compresses the return spring; when the thermostatic element is cooled, the thermostatic element contracts and the return spring pushes the piston back in its original position.
Temperature adjustment:Autotaps thermostatic mixing valves have a temperature adjustment (usually located at the top of the valve). Typically, this can be adjusted to change the position of the piston and therefore the proportion of hot and cold water entering the valve.
Can problems with ‘non-return valves’ cause the temperature control system to fail?Non-return valves can be held open by dirt or grit. In this case, if the mains pressure and hot water pressure differ, hot water can be forced back down the piping system the wrong way through a non-return valve, meaning the water temperature may no longer be regulated.
There are other factors that can causes a thermostat to fail such as an open vented system, localised expansion from water heater, a failed seal in a non-return valve, a particulate contamination and incorrect plumbing. Correct installation and servicing are also essential to ensure that filtration measures and checks on the product are performed.
Can the heating system influence the performance of TMVs?It is important that the installation method and technical parameters in our instruction booklet is adhered to as failure to do so may prevent the valve from operating correctly.
Common installation errors are:
1. Failure to use flow regulators when installing a thermostatic product to a combi boiler system. This may cause performance issues during winter months.
2. Failure to remove flow regulators when installing to a vented system, i.e. a traditional immersion heater. This may reduce the water flow.
What's the difference between ATV-9004C and ATV-9004B?
They're litterally both the same thing, except for only one difference.
ATV-9004B has a 'wall-mounting' brackets attached to it, while ATV-9004C has a 'female' connection end, which can be connected directly to a control box water 'inlet' supply.
We have electronic taps which are versatile; can be powered by batteries or electric or both. Some of our sensor taps have temperature adjustment controls, which allow the temperature to be manually adjusted according to user's preference.
All our automatic taps are suitable for education, retail, home, public, offices, industrial and health care applications.
We have introduced new control boxes for our sensor automatic taps to expand Autotaps product offering and adapt to the dynamic requirements we are beginning to see in different commercial and domestic niches. Our bold new designs are constructed using the highest quality standard and reliability.
We are a one-stop source for electronic infrared sensor taps and nothing else. We only focus on sensor taps, which gives us the ability to create well-rounded high quality products.
We always ensure that we capture today’s design styles and trends, Autotaps products possesses ‘low arc’ and ‘high arc’, swivel-neck construction styles that gives our automatic taps a smooth, updated look to any style of sink.
Autotaps Limited have designed and manufactured commercial solid brass taps, and we are today’s industry exclusive source for electronic taps, plumbing fixtures and accessories. We aim to supply commercial sector, industrial, health care, recreation, education, and restaurant markets worldwide.
Autotaps sensor taps incorporate state-of-the-art infrared technology that's stable, reliable with highest quality and fastest response time.
All our taps feature water conservation of around 0.5 gallons per minute (GPM) with vandal-resistant body structure. They are drip-free designs, and electronically activated using state-of-the-art infrared technology activation.
Everybody is driven by the growing concern over germs on toilets and washroom surfaces, and an increasing number of commercial, private, and public buildings are now installing automatic taps, flushers, cleaning systems, and other touch-free sensor devices. In addition to sanitation issues, other factors are also contributing to this trend.
One technology that has had the biggest impact is infra red sensor.
The infra red sensors allow public restroom tap fixtures to operate without the user's ever touching a button, tap or the handle.
They have been solid performers, and builders and architechs installed them in washrooms, kitchens, restuarants, schools, homes, offices etc, with an estimated 15 to 20 percent of new commercial buildings adopting the technology
