Information

Cooling batteries are designed to be installed into ducted ventilation systems to cool the air that passes through them. There are ranges suitable for fitting to either round duct or to rectangular duct.

There are two generic types - water cooling batteries which would typically have a flow and return of cold water from a chiller to cool the air flow, and DX cooling batteries which would typically be connected to an air conditioner condenser unit.

Cooling batteries typically have a drip tray and drain to deal with the condensed water that will form on the coils when the air is cooled.

Puravent’s range of cooling batteries includes cold water cooling batteries and DX cooling batteries by leading manufacturers Systemair and Veab. Browse our categories to find the right product for your application or if you require any further assistance, please call us on 01729 924108 to discuss your requirements.

Heat Load	Watts	BTU
Average The Room Is A Normal Residential Room, Office, Reception Area Or Similar, Where There Is Not Overly Crowded With People, Computer And Office Equipment.
Above Average There Are Factors That Contribute To Additional Heat Being Generated In The Room E.G. Strong Lighting, Overcrowding With People And Office Equipment, Conservatory Type Room, Or Flat Roofed Room.
High There Are Factors That Contribute To A High Heat Load In The Room. E.G. Commercial Cooking, Much Computer And Server Equipment, Switchgear, Temporary Building With Thin Walls And Flat Room, Plain Glass Conservatory.

Variable	Units	Notes/Guidance
System Airflow	M3/Hr	If you have it in cfm then multiply your cfm value by 1.7 to get m3/hr
Average Combined Pressure Drop Of Filters Of Higher Than F6 Efficiency	Pascals	F8 bag filters pressure drop - typical clean clean to dirty, 160 - 250 Pascals F9 compact filters pressure drop - typical clean to dirty, 160 - 350 Pascals H10 HEPA filter pressure drop - typical clean to dirty, 250 - 600 Pascals 9.8 Pascals = 1 mm wg, & 249 Pascals = 1 inch wg
Carbon Filters Pressure Drop	Pascals	For compact type carbons pressure drop between 100 - 150 Pa Bonded carbon panels typically 150 - 170 Pa Loose granular carbon panels typically 130 Pa
Annual Operational Hours	Hrs/Annum	8760 hours in a year If operating for 5 days a week, excluding public holidays, for 12 hrs/day = 3000 hrs
Cost Of Power	Pence Per Kwh	Huge variance in what different companies pay. heck your last bill to be sure, otherwise put in 10p
Fan Efficiency	(As Decimal Value, Eg 100%=1)	Would typically be around 60%, so if you don’t have specific information use 0.6
Fan Motor Efficiency	(As Decimal Value, Eg 100%=1)	Larger motors should be around 90%, so if you don’t have specific information use 0.9

This Pressure Drop Is Costing In Energy Alone	£	Per year
It Is Probable That A Sanuvox In-Duct System Could Break Down The Biological, Chemical And Odourous Contaminants On This Air Flow For Between 16 And 25% Of This Running Cost	£	Lower energy cost estimate of an equivalent Sanuvox system (16%)
