Shreya Electricals is the leading manufacturer of HVAC panels. DDC is often used to control the HVAC (heating, ventilating, and air conditioning) devices such as valves via microprocessors using software to perform the control logic. Such systems receive analogue and digital inputs from the sensors and devices installed in the HVAC system and, according to the control logic, provide analogue or digital outputs to control the HVAC system devices. These systems may be mated with a software package that graphically allows operators to monitor, control, alarm and diagnose building equipment remotely. Our range is available in different specification to meet varied needs of client.
