The Brain simplifies your hot water system to deliver unparalleled accuracy, stability and safety. It offers programable temperature alerts and a program to promote compliance with recommended Legionella guidelines

The Brain analyses data to track behaviour and performance as an integral component of a hot water system operation. Following a standard of care with it, we can minimize the risk of scald injury, Legionella-related illness and the associated litigation.

The ability to very accurately, deliver tempered water at 52˚C to the entire hot water network greatly reduces the risk of scalding from every fixture. This can remove the requirement for thermostatic mixing valves (TMV’s). Eliminating TMV’s from bathrooms reduces room entry necessary for maintenance, which, in the case of hotels can cause revenue loss, or in hospitals increase risk of bringing dirt and bacteria into the medical space. Even if the decision is to use TMV’s by limiting the hot water temperature to the fixture, increased safety is guaranteed in the event of a TMV failure.

Industry Leading Temperature Control

• Hot water always within specification
• Fast – full stroke in 1.5 seconds
• Flexible – over-sizing not an issue
• Better hot water control improves performance of POU mixers
• Predictable

Performance

• +/- 1°C control at all flows
• 0.5°C minimum system temperature loss

Smarts

• Component self – diagnostics
• Programmable set points & alerts
• Programmable Thermal disinfection

Safety

• Over temperature shutoff
• Power failure shutoff
• Emergency mode

The advantage, to the owner of eliminating or reducing the number of TMV’s in the building, is that the cost of installing the hot water system is greatly reduced -often by around 50%

Circulating the hot water around the building at 52˚C , rather than 60˚C, saves energy – by reducing the heat losses in the hot water loop and thus the cooling load on the building.

With integrated systems (The Brain, solar water heaters, heat pumps, calorifiers, & boilers) for generating hot water, now common , maintaining accurate temperature control can often be difficult. The installation of Brain between the hot water generation plant and the user is an intelligent system operation protocol that will always ensure the comfort and safety of users and from every bathroom fixture.
