SITC of Air-Cooled Chiller

SITC of Air-Cooled Chiller

(Supply, Installation, Testing & Commissioning)

An air-cooled chiller is a self-contained cooling system widely used in commercial buildings, hospitals, hotels, IT parks, and industrial facilities, especially where water availability or cooling towers are a constraint.
SITC ensures the chiller plant is delivered end-to-end—from approved equipment supply to a fully operational, performance-verified system.

1️⃣ Supply (S)

Procurement and delivery of consultant-approved equipment and accessories:

• Air-cooled chiller(s) (scroll/screw, inverter as specified)

• Primary/secondary chilled water pumps

• Buffer tank (if specified)

• Piping, valves, strainers, expansion tank

• Insulation & cladding

• Electrical panels, controls & BMS points

Checks at Supply Stage

• Capacity (TR), COP/IPLV, design ΔT

• Ambient derating suitability

• Noise level compliance

• Accessories and spares as per BOQ

2️⃣ Installation (I)

 Chiller Placement & Mounting

• Installation on RCC plinth / rooftop steel structure

• Adequate air clearances for condenser airflow

• Vibration isolation (springs/rubber pads)

• Proper drainage for condensate and rainwater

 Air recirculation at condenser is a common performance killer—clearances matter.

 Chilled Water Piping

• Correct pipe sizing as per hydraulic design

• Qualified welding / grooving practices

• Hydrostatic pressure testing before insulation

• Proper insulation with vapor barrier to prevent sweating

 Pumps, Valves & Accessories

• Pump alignment and rotation checks

• Installation of:

  • Isolation valves

  • Balancing valves

  • Strainers

  • Air vents & drains

 Electrical & Controls

• Power cabling with proper earthing

• Control wiring and interlocks

• Integration with BMS / EMS

• Phase sequence and protection checks

3️⃣ Testing (T)

Testing ensures the system is safe and ready to operate:

• Hydrostatic testing of piping

• System flushing and cleanliness verification

• Electrical insulation & continuity tests

• Pre-start checks for compressors, fans, pumps

• Safety interlock testing (HP/LP, flow switches)

4️⃣ Commissioning (C)

Commissioning proves the system performs as designed:

• Initial start-up as per manufacturer SOP

• Water flow balancing across circuits

• Verification of ΔT, capacity, and power consumption

• Part-load and full-load performance checks

• Noise and vibration measurements

• BMS point-to-point testing

Joint witnessing with consultant/PMC is recommended.

Documentation & Handover

• Test & commissioning reports

• As-built drawings

• O&M manuals

• Warranty certificates

• Operator training and SOPs

Applications

• Commercial offices & malls

• Hospitals & healthcare

• Hotels & institutions

• Data centers (edge/backup)

• Industrial process cooling

Why SITC Matters for Air-Cooled Chillers

• Single-point responsibility

• Faster commissioning

• Predictable performance

• Lower lifecycle risk

In Simple Words

SITC of an air-cooled chiller means supplying, installing, testing, and commissioning a complete chiller plant that is ready for operation and meets design performance.
