HVAC Control for Facilities Management

Facilities management, HVAC Control Systems & BMS

A heating, ventilation and air conditioning system (HVAC Control) is generally controlled through a facility’s BMS system. Typically BMS sensors and control signals will be hardwired throughout the building during construction for cost control purposes. However, once the building is complete and in operation further expansion to the BMS system due to remodelling or increased requirements can be costly and very disruptive, not to mention putting a strain on the original system capacity.

Our range of environmental monitoring transmitters can be strategically positioned throughout a building providing cost-effective, non-disruptive installation. As part of a wireless system the MS1000 control modules can be interfaced to an existing BMS system. The MS1000 modules will wirelessly replicate the signals generated by the sensors which can be read by the BMS system eliminating the requirement for cable between the sensor and the BMS system. Alternatively, a single receiver is available providing Modbus RTU data directly to the BMS system.

Critical equipment and plant monitoring and control

Generating alarms within a building has a range of applications within the plant room setting, including boilers, chillers, electrical equipment, water tanks and pumps. When levels exceed pre-determined limits, alarms are generated automatically to notify facility managers that a situation has occurred which could result in damage to the organisation.

The RL4805/6 or SMS module can be used for a number of applications including measuring low or high levels, flood, temperature boundaries and many more. The product alerts maintenance staff immediately via SMS notification.

When immediate alarm notification of unacceptable conditions is required, Hanwell wireless alarm sensors provide multipoint alarm notification throughout a facility allowing preventative action to be taken. When used in conjunction with MS1000 modules, secondary power generators can be automatically engaged or electrical circuits can be enabled or disabled depending on the action required.

Internal and external building maintenance and control

Water ingress or leaks can result in many thousands of pounds worth of damage to a building’s structure or contents and result in ineffective stock and costly downtime. Flood/leak detection is a cost-effective way to avoid damage and associated costs. Similarly, the damp generated by overflowing gutters is a serious and costly threat to a building’s structural integrity. Both of the above are easily avoidable with our simple Watch solutions.

Our RL4805/6 product is specifically designed for the detection of water leaks. Where flood detection is required as an integral part of a building management system (BMS) wireless flood detection transmitters are available.

The GutterWatch has a unique sensor specifically designed to alert building maintenance experts to gutter overflow, which is usually caused by simple blockages such as foliage or bird carcasses.

Ambient temperature and humidity for building monitoring and control

Inappropriate humidity levels can cause a range of respiratory infections, trigger allergies and generate unacceptable levels of static. High levels of static can cause damage to sensitive equipment within the facility.

The Hanwell Pro 4000RHT series and Hanwell IceSpy RHT transmitter offer a broad solution for accurate and reliable data gathering. The wireless transmitters have the advantage of being continuously connected to the monitoring system removing the need for valuable staff time in downloading data loggers also removing the danger of human error.
