The Energy Service Business Unit, formerly Swat Energy Technology, was acquired by Cheng Long Intelligent Engineering in 2013. In 2017, the name was changed to Cheng Long Energy Technology. It was honored as an excellent ESCO for three years in a row, and can provide a total energy solution for the customer. Measures to improve energy conservation can be done in two ways:


Upgrading existing system or equipment:
Upgrading the performance of existing system or equipment to achieve the goal of reducing energy consumption and cutting costs.
Installing energy conservation system or equipment:After helping users evaluate the risks and costs, help users install appropriate energy conserving equipment or system to replace the existing equipment or system in order to achieve the goal of energy conservation and high efficiency operation.

Water heater - The heat pump works similarly to an air conditioner: it performs heat exchange with the heat in the environment or the waste heat from the air conditioning system and uses it to heat up water used in every day life. The hot water system is energy efficient, eco-friendly, and safe.
Upgrading existing system or equipment:
  • Replacing boiler equipment
  • Changing the boiler fuel supply system (From crude oil to diesel or natural gas)
  • Adjustment and control of the boiler air-fuel ratio
  • Improvements to the economizer and heat recovery
  • Improvements to heat insulation of piping and hot water tank
installing energy conservation system or equipment:
  • Installing heat pump water heater to replace the existing hot water supply system
  • High temperature heat pump water heater
  • Mid-to-low temperature heat pump water heater
  • Designing heat pump water heater preheat system.
  • Establishing and integrating heat recovery system
