When Silence is Golden and Less is More

An HVLS fan by Bigass Fans for 24′ blades with a power rating of 2.0 hp (1.5 kW) weighs 347 lbs. (157 kg) and draws in 30A from a single phase 200-240V connection. It rotates at 65 rpm and torque output is unknown.

An HVLS Fan with Epoch 4.0 motor and drive system with a power rating of 2.4 hp (1800 W) weighs 275 lbs. (125 kg) and draws in 10A from a single phase 230V connection. It rotates at 70 rpm with a torque output ranging from 220 to 300Nm.

That is a weight saving of 72 lbs. (33.7 kg) with a three times improvement in the efficiency from 30A to 10A. That is not to discount the fact that an HVLS fan with an Epoch platform runs at a noise level of less than 35 dB and never requires any maintenance of what so ever nature.

An HVLS Fan with Epoch 3.0 motor and drive system with a power rating of 2.0 hp (1500 W) weighs 218 lbs. (99 kg) and draws in 9A from a single phase 230V connection. It rotates at 70 rpm with a torque output of 170Nm.

That is a weight saving of 129 lbs. (58 kg) with a more than three times improvement in the efficiency from 30A to 9A. That is not to discount the fact that an HVLS fan with an Epoch platform runs at a noise level of less than 35 dB and never requires any maintenance of what so ever nature.

An HVLS Fan with Epoch 2.0 motor and drive system with a power rating of 1.5 hp (1100 W) weighs 194 lbs. (88 kg) and draws in 6A from a single phase 230V connection. It rotates at 55 rpm with a torque output of 90Nm.

That is a weight saving of 153 lbs. (69 kg) with a more than six times improvement in the efficiency from 30A to 6A. That is not to discount the fact that an HVLS fan with an Epoch platform runs at a noise level of less than 35 dB and never requires any maintenance of what so ever nature.

Epoch is a point in time beginning a new or distinctive period. Today you have arrived at that point. Today we enter a new era.

When Silence is Golden
When less is more
We are sending the gear box to the outer space

 

An HVLS fan with EPOCH technology comes with

  1. extraordinary quietness (Silence is Golden);
  2. the least amount of components and complexity (Less is More) and hence highest reliability and performance;
  3. extraordinary safety and strength;
  4. the mechanical design of a very high safety factor;
  5. amazingly efficient and optimum motor and drive technology;
  6. or without an integrated controller;
  7. the single phase power input of 90 to 277 VAC (50 or 60 Hz);
  8. unity power factor correction (absolute no wastage of power due to poor power factor);
  9. 95%+ efficient drive and controller;
  10. a safety margin of three times for drive electronics;
  11. drive electronics having dual processor control;
  12. sensorless control of brushless permanent magnet motor;
  13. removable and serviceable controller and drive electronics;
  14. scalable motor architecture from 25 to 450Nm+;
