HEMCO Product Lines We Repair
Our engineers are trained on the full HEMCO product range. Below are the major product families we service.
HEMCO Fume Hoods - Variable Air Volume (VAV) Control Systems
HEMCO VAV fume hoods utilize electronic airflow regulation to maintain constant face velocity (typically 80-120 linear feet per minute) while optimizing energy consumption. Common repairs include VAV damper actuator failures, airflow sensor malfunctions, and control board faults that cause erratic sash behavior or face velocity warnings.
HEMCO Biosafety Cabinets - Class II Type A2/B3 with Smart Controls
HEMCO biosafety cabinets integrate electronic monitoring for airflow integrity, HEPA filter status, and UV light operation. Repair challenges include airflow sensor circuit failures, differential pressure transducer drift, interlock relay malfunctions, and smart control module software resets affecting sterility assurance.
HEMCO Ductless Recirculating Fume Hoods - Filter Monitoring Electronics
HEMCO ductless hoods use integrated filter life monitoring, activated charcoal saturation detection, and motor speed controllers. Typical failures include filter differential pressure sensor faults, activated charcoal saturation indicator circuit failures, and blower motor speed control electronics malfunction.
HEMCO Sash Position Sensors and Interlocks
Safety-critical magnetic reed switches and proximity sensors that detect fume hood sash position and trigger interlock relays for UV light cutoff and alarm notification. Common faults include sensor misalignment, relay contact corrosion, intermittent sash detection, and failed protective relay modules.
HEMCO Airflow and Differential Pressure Sensors
HEMCO employs capacitive differential pressure transducers and ultrasonic airflow sensors for real-time hood performance monitoring. Failures manifest as zero/inaccurate sensor readings, drifted calibration, intermittent signal loss, or damaged transducer diaphragms causing false alarms.
HEMCO Smart Control and Data Logging Systems
HEMCO's integrated control platforms log airflow compliance data, HEPA filter service intervals, and maintenance history via networked PLC modules and touch-panel HMIs. Repair issues include Ethernet port failures, SD card data corruption, touchscreen unresponsiveness, and PLC firmware update failures.

Common HEMCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HEMCO equipment arriving at our workshop.
- ✓VAV Damper Actuator Stuck or Non-Responsive — HEMCO VAV damper actuators (typically pneumatic or electric) fail due to dust accumulation in the damper shaft, spring fatigue from thousands of position cycles, or loss of air pressure in pneumatic actuators. Indian pharmaceutical manufacturing facilities operating in high-particulate environments experience accelerated damper wear.
- ✓Airflow Sensor Reads Zero or Drifted Values — HEMCO differential pressure and ultrasonic airflow sensors drift or fail due to sensor diaphragm damage from pressure spikes, contamination buildup on sensing ports, or electronics board capacitor degradation. High-humidity laboratory environments (common in Indian biotech facilities) accelerate PCB corrosion.
- ✓Sash Position Interlock Relay Fails - UV Light Does Not Shut Off — HEMCO interlock relays (safety-critical for UV sterilization shutoff) fail due to contact corrosion from moisture and laboratory chemical vapors, coil insulation breakdown, or mechanical contact wear. Failure prevents automatic UV lamp cutoff when the sash is raised, creating personnel safety hazards.
- ✓Control Board Touchscreen Unresponsive or Displays Wrong Data — HEMCO smart control panels use resistive or capacitive touchscreens that fail due to connector corrosion, static discharge damage to driver electronics, firmware glitches, or failed LCD backlight circuits. Exposure to laboratory aerosols and cleaning chemicals accelerates connector oxidation.
- ✓HEMCO Blower Motor Speed Does Not Respond to Control Signals — HEMCO ductless hood blower motors are controlled by PWM (pulse-width modulation) or 0-10V analog speed controllers that fail due to MOSFET burn-out from voltage transients, motor winding insulation failure, or loose speed feedback sensor connections in the motor tachometer circuit.
- ✓HEPA Filter Saturation Sensor Shows Incorrect Status — HEMCO activated charcoal saturation and HEPA clogging sensors use differential pressure or carbon-dioxide detection that malfunctions due to sensor port blockage, electronics module power supply failure, or calibration drift after long service intervals typical in busy Indian research facilities.

Frequently Asked Questions — HEMCO Repairs
Do you repair HEMCO equipment anywhere in India?+
Yes. Synchronics repairs the full HEMCO laboratory ventilation and containment equipment range - fume hoods, biosafety cabinets, VAV controls, airflow sensors, and smart monitoring systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. Same facility in Vadodara, Gujarat. Most HEMCO repairs are completed within 5-7 working days.
My HEMCO biosafety cabinet shows a low airflow alarm but the HEPA filter is new. What could be wrong?+
A new HEPA filter combined with persistent low airflow alarm typically indicates a faulty differential pressure transducer, blocked sensor intake port, or miscalibrated airflow sensor rather than actual filter clogging. Synchronics performs diagnostic testing of the pressure transducer (0-2.5 inWC range), cleans sensor ports, and recalibrates the sensor interface board. We also verify downflow and inflow velocities with an independent anemometer to confirm actual hood performance before clearing the alarm.
Can Synchronics replace just the control board or do I need to buy a whole new HEMCO fume hood?+
Synchronics specializes in board-level and component-level repairs. We replace failed VAV controllers, smart monitoring modules, sash interlock relays, sensor interface boards, and touchscreen controller circuits without requiring hood replacement. Most Indian pharmaceutical labs save 60-70% by repairing control electronics instead of purchasing new hoods. We source genuine HEMCO boards or manufacture compatible replacements with identical functionality and safety certifications.
What is the typical turnaround time for HEMCO sash sensor and interlock relay repairs?+
For HEMCO sash position sensors and safety interlock relays, Synchronics provides a 3-5 working day standard turnaround. We test sensor alignment, replace corroded relay contacts or entire relay modules, and verify full interlock operation (sash position detection + UV lamp shutoff) before handover. Expedited 24-48 hour service is available for critical biosafety cabinet repairs affecting laboratory operations.
Does Synchronics offer preventive maintenance contracts for HEMCO laboratory equipment?+
Yes. Synchronics provides annual and bi-annual preventive maintenance contracts for HEMCO fume hoods and biosafety cabinets across Indian pharmaceutical, biotech, and research facilities. Contracts include quarterly sensor calibration, relay testing, filter saturation reset, firmware updates, and documented airflow verification reports. We also offer spare parts kits (sensors, relays, capacitors) at competitive rates to minimize downtime during emergency repairs.
How do I send my HEMCO 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 HEMCO 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 HEMCO 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 HEMCO 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.
