Why Have Two Thermostats on VAV Diffusers?
Why Have Two Thermostats on VAV Diffusers? When selecting thermostats for thermally powered diffusers it is necessary to take into account the effects of stratification, radiation and conduction. The limited range of a single thermostat will not extend over a comfort range which must be biased lower for cooling and higher for heating. In order […]
Adjustable Constant Airflow Regulators
Adjustable Constant Airflow Regulators (CAR’s) are modulating device that automatically regulate airflows in duct systems to constant levels, Exhaust or Supply Air. The passive control element responds to duct pressure and requires no electric or pneumatic sensors or controls. The CAR unit compensates for changes in duct pressure caused by thermal stack effect, building pressure, […]
Installing a Drying Room Could Save Your Building
Protect Your Environment Even when you cannot see it, moisture in the form of water vapour is all around us, held in suspension in the air. The relative humidity of the air, in many cases determines the extent of corrosion of certain materials, the speed at which moulds develop and the rate of increase in […]
Pressure Relief Venting for Stairwell Pressurisation
The pressurisation of stairwells is an increasingly common method of ensuring a safe means of exit from a building on fire. Pressure control must be in place, to maintain minimum & maximum stairwell pressures, within agreed parameters. Apreco’s range of standard pressure relief vents are characterised by ease of installation. For internal siting, the blade […]
