HANKISON Product Lines We Repair
Our engineers are trained on the full HANKISON product range. Below are the major product families we service.
HES Series Refrigerated Dryers
Energy-efficient refrigerated dryers for general industrial compressed air drying. Common repairs include compressor failures, condenser leaks, expansion valve jams, and thermostatic element degradation due to moisture ingress.
AD Series Desiccant Dryers
Heated regenerative desiccant dryers delivering ultra-low dew points for pharmaceutical and electronics manufacturing. Typical faults: heater element burnout, solenoid valve sticking, desiccant cartridge saturation, and PLC control failures.
SED Series Super Efficient Dryers
Advanced econo-dryers combining refrigeration and desiccant technology. Common issues: dual-circuit control valve malfunction, thermal bypass blockage, and sensor calibration drift affecting dew point regulation.
ADX Series Advanced Desiccant Dryers
Premium desiccant dryers with advanced PLC monitoring and adaptive regeneration. Repairs often needed: touchscreen display failures, Modbus communication faults, solenoid isolation valve leaks, and desiccant saturation detection sensor malfunction.
Filtration and Separator Modules
Compressed air filters, moisture separators, and after-cooler units. Common defects: clogged filter cartridges, condensate drain valve seizure, element sealing ring degradation, and bypass valve spring failure.
Electronic Control Boards and Sensors
PLC modules, temperature sensors, dew point transducers, and digital displays for Hankison dryers. Typical repair needs: PCB corrosion from moisture, temperature sensor open/short, display panel failure, and relay burnout.

Common HANKISON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HANKISON equipment arriving at our workshop.
- ✓Refrigerated dryer compressor fails to start — Hankison HES series compressors often encounter capacitor degradation in India's high-temperature environment (40-45°C ambient). Thermal overload sensors may also trip due to dirty condenser fins blocking airflow in dusty manufacturing areas.
- ✓Desiccant dryer heater element burns out prematurely — Hankison AD and ADX series heater elements fail due to electrical surges (common in Indian power grids) or moisture-induced corrosion inside the heater sheath. Wet desiccant cartridges also force heaters to work harder, accelerating burnout.
- ✓Dew point sensor reading incorrect or drifting — Hankison ADX and SED dryer dew point transducers (typically ceramic or capacitive sensors) drift due to condensate film buildup inside the sensor probe or silica contamination from damaged desiccant cartridges.
- ✓Solenoid isolation valve stuck or leaking — Hankison AD/ADX dryer solenoid valves experience coil burnout from voltage fluctuation or valve spool sticking due to mineral deposits from untreated incoming air. Condensate backflow also damages valve seals.
- ✓PLC controller stops communication or display blank — Hankison HIC controller and digital display modules fail due to humidity-induced PCB corrosion, loose wire terminals from vibration, or software crashes from power interruptions. Modbus RS-485 communication lines also short in humid environments.
- ✓Condensate drain valve blocks or floods dryer — Hankison SED and HES series condensate drains accumulate mineral deposits and sludge in Indian hard-water regions. Drain solenoid coils also fail, causing valves to remain open and saturate desiccant cartridges or leak oil.

Frequently Asked Questions — HANKISON Repairs
Do you repair Hankison equipment anywhere in India?+
Yes. Synchronics repairs the full Hankison compressed air treatment portfolio — refrigerated dryers (HES, SED), desiccant dryers (AD, ADX, Super Dry), filtration modules, and electronic control systems. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. All repairs are completed in our Vadodara, Gujarat facility with genuine Hankison parts and comprehensive testing.
What is the typical repair turnaround time for a Hankison dryer?+
Turnaround depends on fault severity. Minor repairs (solenoid valve cleaning, sensor recalibration, display replacement) take 2-3 days. Major overhauls (compressor rebuild, heater element + cartridge replacement, PLC re-programming) take 5-7 days. Emergency expedited service available. We provide daily status updates via email and phone.
Why does my Hankison AD series desiccant dryer lose dew point after 3-4 months?+
In India's humid climate, desiccant cartridges in Hankison AD dryers saturate faster due to high inlet humidity and regeneration efficiency losses. Synchronics recommends: (1) Check inlet air filtration — dirty filters block regeneration airflow. (2) Verify heater element temperature — faulty elements cannot fully reactivate desiccant. (3) Replace desiccant cartridge if inlet humidity exceeds 80% RH — preventive replacement every 6 months is cost-effective. We can also upgrade your regeneration system for improved efficiency.
Can you supply original Hankison spare parts or only repair my unit?+
Synchronics repairs your equipment using genuine Hankison OEM parts and components. We maintain stock of common parts (heater elements, solenoids, sensors, desiccant cartridges, filter elements) for rapid turnaround. For rare or discontinued parts, we source directly from Hankison's India network. We do not sell standalone parts retail — repair service includes all necessary components and labor.
My Hankison HES refrigerated dryer trips thermal overload constantly in summer. What should I do?+
Thermal overload trips in Hankison HES dryers during summer (April-June) indicate condenser airflow restriction or compressor mechanical load increase. Synchronics diagnosis: (1) Clean condenser fins and verify ambient intake airflow. (2) Test compressor discharge pressure — if exceeding 8.5 bar, head valves need cleaning. (3) Check capacitor health — degraded capacitors cause motor strain. (4) Verify cooling water circulation (if water-cooled model). We recommend annual maintenance before summer season to prevent costly downtime. Call us for preventive service.
How do I send my HANKISON unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a HANKISON drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on HANKISON repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your HANKISON unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
