Specialized in industrial waste heat recovery and heat-exchanger applications, delivering end-to-end energy-saving solutions — from process diagnosis → design → equipment selection → manufacturing & installation → O&M optimization — turning every bit of waste heat into value.
Yang Kun has long been dedicated to industrial waste heat recovery and heat-exchanger applications. He is familiar with plate, heat-pipe, rotary, and stainless-steel high-temperature air-to-air heat exchangers as well as various non-standard units, serving mines, data centers, agricultural & food drying, pharmaceutical, chemical and commercial HVAC scenarios.
Built on the mature heat-exchanger industry cluster of Zibo, Shandong and its R&D/manufacturing system, he provides turnkey waste heat recovery — not just selling equipment, but taking responsibility for the energy-saving outcome.
The affiliated company QIYU (air69.com) was founded in 2005 in Zibo, Shandong. It is a provincial "Little Giant" (specialized & innovative) high-tech enterprise with 160+ heat-exchanger patents, covering thermal calculation, structural design, precision manufacturing and factory acceptance testing.
From a single heat-exchanger replacement to a plant-wide waste heat cascade utilization retrofit, Yang Kun delivers reliable, measurable turnkey results.
A six-step closed loop, accountable for the energy-saving result from the first consultation to long-term operation.
On-site or remote survey of heat sources, heat-demand sides, medium parameters, operating conditions and the existing energy baseline.
Thermal calculation, equipment matching and system energy simulation, with quantified savings and ROI estimates.
Plate / heat-pipe / rotary / stainless high-temp custom units, built on a mature production line with pre-ship hydrostatic testing.
Seamless connection to existing production lines, HVAC or process piping, minimizing construction and downtime.
On-site guidance or EPC, including interlock commissioning, parameter tuning and acceptance handover.
Energy-efficiency monitoring, scheduled maintenance and continuous optimization to sustain the designed recovery rate.
Covering mainstream air-to-air and waste heat recovery technologies, with non-standard customization per process.
Sensible and total-energy (membrane) types — compact, low pressure drop, for HVAC and no-humidity-transfer systems.
Passive gravity heat-pipe transfer with no moving parts — ideal for ventilation, HVAC and dryer exhaust recovery, maintenance-free.
Rotating matrix continuously transfers sensible & latent heat; high recovery (dehumidification 70–85%) for large-airflow HVAC.
All-welded stainless plate pack, 350℃ resistant, corrosion-proof and leak-free — for flue gas / hot-air heat recovery.
Placed before/after the cooling coil — pre-cooling & dehumidification upstream, reheat downstream, cutting reheat steam use.
Intermediate liquid loop links two exchangers, transporting distributed waste heat to the point of use for cascade utilization.
Tailor-designed to medium, temperature, pressure and space constraints; high-temp, high-pressure (3.0 MPa) and corrosive service.
Plant-wide waste heat cascade diagnosis and retrofit — energy audit, design and turnkey implementation.
Process matching, selection calculation and technical consulting to achieve quantified savings with minimal investment.
Different processes call for different technologies — below are proven deployment scenarios.
Exhaust heat recovery — heat-pipe / plate preferred (no rotary wheel), for intake-air heating and space warming.
Server cooling waste heat recovery — plate / IEC preferred (no rotary wheel) to help optimize PUE.
Drying exhaust sensible heat recovery uses plate sensible exchangers; U-tube heat pipe only as dehumidification backup.
No recirculation of exhaust — sensible recovery keeps purification safety while reclaiming waste heat.
Process exhaust and high-temp flue gas recovery with corrosion-resistant, high-temp custom design and integration.
Fresh-air / exhaust energy recovery via total-energy or rotary wheels, cutting HVAC load and operating cost.
