Compressor Details Of The Chemical Processing Glycol Chiller:

(1) All Darko water-cooled screw chillers utilize globally renowned semi-hermetic screw and reciprocating compressors from premium brands such as Hanbell, Bitzer, and REFCOMP.

(2) Featuring a 5:6 gear ratio dual-screw configuration and advanced linear design, these compressors achieve energy efficiency, environmental compliance, superior performance, and ultra-low noise levels (<55 dB(A)).

(3) Configurable with single or dual compressor circuit systems based on cooling capacity requirements. The compressors automatically alternate operation in response to load variations, ensuring balanced runtime distribution across units. This intelligent design extends equipment service life significantly, delivering >45,000 hours of maintenance-free operation.

Heat Exchanger Of The Glycol Chiller 

(1) Equipped with double-thread reinforced tubes for enhanced structural integrity.

(2) Internally ribbed copper tubes with smooth external surfaces optimize heat exchange efficiency (ΔT ≤1.5°C).

(3) Designed using CFD-validated CAD technology and precision CNC-machined for compact dimensions (±0.1mm tolerance). The 25mm PE insulation layer ensures <3% cold loss and eliminates condensation risks (ambient RH ≤85%).

(4).Constructed with heavy-gauge copper tubes processed into trapezoidal low-resistance configurations, enhancing heat transfer coefficients (*U-value ≥3,500 W/m²·K*). The smooth tube surfaces reduce hydraulic resistance (ΔP <25 kPa) and facilitate CIP (Clean-in-Place) operations.

Protection Systems:

Integrated safeguards include:

Temperature/pressure limit switches (ASME B31.3 compliant)

Dual-stage overload protectors (IEC 60947-4-1 certified)

Compressor anti-short-cycle modules (≥15-minute restart delay)

Multi-color HMI fault indicators (IP65 rated)

Control System:

Darko’s proprietary PLC-PC hybrid control platform enables:

SCADA-compatible remote monitoring (Modbus RTU/TCP protocols)

Plug-and-play installation (CE/UL listed components)

Siemens S7-1200 PLC integration (optional)

User-defined parameterization via 10.1" industrial HMI (EN ISO 13849-1 PLc)
