Save money on cooling
In most circumstances, Vent-Tech’s evaporative cooling solutions provide a much more cost-effective and environmentally friendly alternative to industrial air conditioning systems.
Traditional air conditioning uses a number of fans as well as refrigerant gases to achieve the desired air temperature. In contrast, Vent-Tech’s evaporative cooling systems use just one fan to draw the hot air across water on the way in, and one fan to vent the hot stale air on the way out. This achieves the desired cooling with a much reduced requirement for electricity.
Compare the costs
| Evaporative air cooling | Conventional air conditioning |
| 90% reduction in electricity consumption | High electricity consumption by system components |
| No refrigerants used | Uses environmentally damaging refrigerants |
| Supplies 100% fresh cooled air | Provides mainly (80-85%) recycled air |
| Low carbon dioxide footprint | High carbon dioxide footprint |
| Performance improves at high temperatures | Performance reduces at high temperatures |
Greener air conditioning - it's simple...
The eco cooling systems Vent-Tech installs are much simpler than traditional industrial air conditioning systems. Because they have far fewer moving parts, they need much less electricity to run them.
Our solutions utilise the air from outside, and only actively cool it when necessary. This is in stark contrast to standard air conditioning, which generally runs all the time to maintain a constant temperature.
The bottom line: a better, more pleasant, lower cost working environment.
Vent-Tech helps organisations to improve their working environment, save running costs (typically 90% saving on running costs versus standard air conditioning), and slash their carbon footprint by a substantial amount.
Cost and electricity saving
Running costs for evaporative cooling are a fraction of air conditioning running costs. Typically a 1.5kW motor provides over 40kW of cooling. This is compared to more than 15kW of electricity for conventional air conditioning to generate the same amount of cooling.
Comparative costs and consumption of a typical server room evaporative cooling system vs air conditioning
The table below shows the comparative costs and carbon usage for a 100kW server room. This is based on pricing of 8p/kWhr and 0.53702 kg/CO₂ per kWhr. Figures will vary according to industry and application.
