Wiring Diagram: 30GTN015-035

Carrier air‑cooled reciprocating chillers are robust, modular chillers best for small‑to‑medium commercial and industrial cooling loads; typical nominal capacities range from about 106–387 kW** (≈30–110 tons) and product families cover roughly 50–400 tons depending on model. For procurement or service in Dhaka, contact an authorized Carrier dealer or Carrier Commercial Systems for local support and spare parts.

Overview

• Product type: Air‑cooled reciprocating liquid chillers using reciprocating compressors.
• Typical capacity range: ~106–387 kW (Carrier 30GTC family) and Carrier literature lists 50–400 tons for similar air‑cooled reciprocating lines.
• Common applications: Small to medium commercial buildings, light industrial process cooling, data closets, schools, and hospitals where modular, staged capacity and redundancy are valued.

Key features and benefits

• Multiple compressor circuits and multi‑compressor arrangements for redundancy and flexible staging. 
• Dual refrigerant circuits on many models to improve reliability and allow partial operation during service.
• ComfortLink microprocessor controls (digital control panel) for simplified operation, sequencing, and diagnostics. 
• Efficient heat exchangers with enhanced tubes for improved heat transfer and lower condensing temperatures.
• Weatherproof enclosures and motor control center options tailored for harsh climates and electrical protection.

Typical technical data to request from the supplier

When specifying or comparing models, ask for:

• Nominal cooling capacity (kW / tons); EER / IPLV or seasonal efficiency; compressor type and count; refrigerant type; number of circuits; power supply and full‑load amps; sound levels (dB(A)); weight and footprint; control features and BMS integration. 

---

Sizing and selection guidance

• Match capacity to peak sensible + latent loads with margin for future growth.
• Prefer multi‑compressor models for partial‑load efficiency and redundancy.
• For Dhaka’s hot, humid climate, prioritize higher condensing capacity and robust weatherproofing; confirm factory options for tropicalization.

---

Maintenance and lifecycle tips

• Regular oil and refrigerant checks, compressor run‑time balancing, condenser coil cleaning, and control firmware updates keep performance optimal. 
• Keep spare compressor valves and control modules on hand for faster repairs in regions with longer parts lead times.

---

Next steps and local action items

• Request product data sheets and installation manuals for the exact Carrier model you’re considering; Carrier’s product literature page and model PDFs are authoritative starting points. 
• Contact an authorized Carrier dealer in Bangladesh for site survey, local pricing, warranty terms, and installation quotes; ask for references of recent local installations and service response times.
