Model Selection & Ordering

Function selection ​

  • Standard type (cooling-heating-hot water).
  • A/C type (cooling-heating).
  • Cooling only type.
  • Condensing Heat Recovery type.

Fuel selection ​

  • Fuels applicable to a DFA can be: natural gas, town gas, LPG, bio-gas, light oil or recycled oil.
  • Natural gas and recycled oil are preferred.
  • Applicable to dual fuel (gas/oil).
  • Different burner matches different fuel.

Load selection ​

  • Building cooling / heating load cannot be estimated, as it is more closely related to building insulation and room function than to building area.
  • Model selection is mainly determined by cooling load. If the heating load is not enough, a HTG enlarged model could be selected.

Quantity ​

  • The fewer units, the lower initial investment and operation cost (as the chiller's COP will be higher and water system's electricity consumption will be lower at partial load).
  • 2 units are recommended for one system (the total capability equals to required load). No need to set standby unit. It is OK to install just one chiller if the chiller is allowed to stop operation once a year.
  • Model 1200, 1600, 2000 could be supplied by modular combination.

Flowrate selection ​

  • BROAD pumpset applies a large temperature difference and low flowrate design so as to save power consumption dramatically.
  • BROAD designs the pump head according to its profound experience.
  • BROAD is open for special head design.

Pressure selection ​

  • The standard pressure limit for chilled/heating/cooling water is 0.8MPa. Information about high pressure type is available on Performance Curves.
  • 0.81~1.2MPa system: select high pressure type.
  • 1.21~1.6MPa system: either extra pressure type or secondary heat exchanger, to be comprehensively evaluated. >1.6MPa system: secondary heat exchange.

Split shipment ​

  • If constrained by access of customers' machine room (or constrained by container transportation), split shipment can be chosen.
  • Split shipment includes two pieces as main shell and HTG. 3 pipes must be connected at jobsite. Customers need to prepare welding instruments, nitrogen and other necessary assistance.

Control ​

  • BROAD chiller and pumpset are equipped with complete control function, including internet monitoring.
  • If users have a building management system (BMS), the BMS control interface can be selected as an optional supply. If the BMS interface is not ordered along with the chiller, it can be purchased later.
  • BROAD BMS is recommended to customers.

Machine room location ​

  • On the floor or on building rooftop.
  • If constrained by facilities, the chiller and the pumpset can be installed in basement while cooling tower on the floor, on stilt or on building rooftop.
  • Enclosure is not suitable for basement installation.
  • Chiller and pumpset should be setup in the same machine room to minimize piping and pressure drop.

Lead time ​

  • ≤ BYZ200: 2~4 months.
  • BZY250~BZY400: 3~5 months.
  • ≥BZY500: 4~6 months.

Warranty ​

Free warranty is to cover 12 months from commissioning or 18 months from shipment, whichever comes earlier. BROAD provides paid service in the whole lifespan. Service price list is available upon request.
