Healthcare and Hospitals

Addressing power quality in healthcare facilities and hospitals offers energy savings, reduced risk of data corruption, and improved life of expensive equipment such as MRI machines. For subsystems involving nonlinear loads, such as computers, electronic lighting ballasts, and X-ray machines, we recommend our harmonic mitigating Distribution TransFilters™. For other areas within healthcare facilities, our ultra-efficient Type e-Rated® transformers provide significant energy savings and attractive financial returns. PQI’s ultra-efficient transformers satisfy ASHRAE design recommendations for healthcare facilities.

Standard Products

 PQI Product  Description  Benefits within Healthcare Facilities & Hospitals
EY (e-Rated®) Ultra-efficient transformer

- Low first cost
- Ultra-low excitation (core) losses reduces power costs

DY & DV Distribution TransFilters™

Harmonic mitigating transformers:
- DY for medium K-Factor loads
- DV for high K-Factor loads

- Reduces power costs
- Reduces penalty losses due to harmonic currents
- Reduces transformer heating and A/C loading
- Reduces THDv to less than 5% at nonlinear loads or motor drivers
- Reduces losses in the loads, thereby reducing A/C requirements 
- Improves switch-mode power supply's 'ride-through' capability
- Balances primary phase currents
- Assures system compatibility with sensitive electronic loads 
- Capable of developing 12-, 18-, 24- and 36-pulse primary systems (with Type DV)
