Why Evacuated Tube Collectors?

Medium temperature process heat (50 degrees C to 120 degrees C) can be produced by ETC collectors due to our innovations. Above 70 degrees C heat typically has been delivered using concentrated solar Thermal (CST). But, ETC can be installed on Industrial rooftops due to its lower weight. Moreover, considerable amount of wasted space on the rooftops can easily accommodate ETC collectors. Simplicity in construction decreases the system price to sometimes even one third. The system does not require continuous tracking according to the movement of the sun, which decreases the operational cost of the system. The overall collection efficiency of ETC collectors is way higher as it also collects diffused light (GHI).

Integrative Concentration

Higher Temperatures up to 120 Degree Celsius are achieved in the modules through various design changes. The series parallel integration of module lets the liquid pass through a number of stages, during which the flow is calibrated and adjusted to reach maximum temperature. The flow, temperature and pressure are monitored and controlled, so that we are able to achieve higher temperature and maintain it constantly.

Auto Hybrid Control System

The system is auto-hybridized by integrating it parallely with the conventional system (boilers, electric heater, etc.).
The continuous monitoring of the temperatures at the ETC modules and the application end helps the auto-hybrid control system to automatically switch between the conventional and the solar thermal systems. This is to ensure that the hot water is delivered throughout the process even when the sun is not available.

Unique structure for Rooftop installation

The panel body is riveted close to the rooftop structure and the evacuated tubes equally spaced, hence the the airflow is not restricted and the force acting on the module is very less, Which prevents the module from uplifting from the roof.
The structures are carefully designed considering both material weight and the standard of the material.

StayLiquidTM

Heat carrying capacity is improved by pressurizing the working fluid which also prevents steaming, cavitation and stuttering.
Heat is then exchanged by using plate heat exchangers,serpentine coils,immersion plate heat exchangers and radiators without any changes to existing heating system.

FlexiFlowTM

Water flow rate,temperature and pressure are adjusted in forced circulation process using control systems to provide optimum conditions for the required heat transfer of the system to produce efficient flow rate based heating systems
