ROYAL EXCHANGE - CASE STUDY. INSTALLATION OF IOT FOR POLYTECK

EnviroLogik working in conjunction with M&E Contractors Polyteck have installed their multi-sensor M&E IOT system in both sub-basement and rooftop plant rooms using their proprietary IOT hardware which was rapidly installed to monitor key items of equipment that the BMS couldn’t.

 

Unlike other systems, the EnviroLogik system is unique in that its systems can communicate and penetrate through sub-basement plant room walls and high-level plant and provide remote monitoring and critical alarming data using a secure Mobile network, enabling monitoring of key items, especially when the site isn’t manned.

 

Special IOT Sensors have been developed and were quickly and easily installed by Polyteck’s technicians to monitor:

  • Chiller Refrigerant Pressures/Leaks

  • Chiller Energy Consumption

  • Plant Room Water Leaks from Heating and Chilled Water Pumps and Sump Pumps

  • Water Tank Temperatures

  • AHU Filter differential pressures

  • Boiler and Chiller Flow Switches

 

Not all IOT systems are the same and some companies are claiming their devices can do many things, but in truth none have a full platform or multi-layered web based Dashboard accessible at different levels by anyone from the Security guards, Building manager, Multi-site Facility Managers and external Contractors.

The open architecture EnviroLogik IOT system can migrate into external systems such as Building Asset and Maintenance/Management systems through an API system and that’s exactly what they have done with Polyteck’s own Multi-Site Planned Maintenance system.

 

Polyteck’s technicians receive instant alerts as soon as something isn’t working quite as it should. Decisions can then be made by key customers staff to fix items before they fail, thereby offering true Condition Based Maintenance.

These IOT sensors, and secure Gateways are not connected to a Wi-Fi, or Buildings ethernet network making them highly secure, and can expand into monitoring many other systems.

 

Just imagine the thousands that can be saved from refrigerant leaks and compressor failures alone.

CASE STUDY - STAPLE INN CHILLER REFRIGERANT PRESSURE MONITORING

The 2 x 180Kw Trane Air Cooled Chillers installed at this site are critical to the comfort of many law firm office workers in this multi-tenanted building.

Chiller failures are commonplace in many Commercial offices are and probably one of the most expensive items to repair. Contractors Polyteck wanted to offer a condition based maintenance service rather than the conventional PPM type contract.

A decision was taken to install the unique EnviroLogik IOT critical refrigerant pressure monitoring and alarming system. The system enables refrigeration specialists to receive immediate alarm exception notifications when the refrigerant pressure drops below pre-agreed parameters within the refrigerant

circuit.

 

 

 

 

 

 

 

 

 

In addition when coupled with the EnviroLogik Chiller Energy Monitoring immediate indicators show that there is increased energy consumption. These 2 indicators show that something is wrong.

The customer can also access high-level less technical information through their own Dashboard, enabling them to request a call out by Polyteck's specialists to fix the problem before the system fails, saving a probable much higher repair bill due to a complete failure and component replacement.

Refrigerant and Compressor failures for a Chiller of this type would easily cost in excess of £10,000
