OLDHAM Equipment We Repair — By Category
OLDHAM Product Lines We Repair
Our engineers are trained on the full OLDHAM product range. Below are the major product families we service.
Flameproof Enclosures & Terminal Boxes
Oldham's heavy-duty flameproof metal enclosures designed for Zone 1 and Zone 2 classified areas. Common issues include cracked or damaged flange seals, corroded threads preventing proper closure, and compromised certification due to improper repairs or modifications.
Cable Glands & Entry Devices
Explosion-proof cable entry systems with brass and stainless steel construction for hazardous environments. Frequent failures include thread stripping during installation, seal degradation under thermal cycling, and corrosion in offshore or chemical plant applications.
Flameproof Push Buttons & Control Switches
Oldham's certified control switches with flameproof construction for operator interfaces in hazardous zones. Typical faults include contact welding, internal arc tracking after fault events, and mechanical binding of push mechanisms due to corrosion or manufacturing debris.
Conduit & Adapter Fittings
Explosion-proof conduit adaptors, elbows, and connectors maintaining flameproof integrity across cable routing. Repair challenges include corrosion at mating threads, loss of sealing compound, and deformed knockouts after repeated disassembly.
Increased Safety 'e' Accessories
Non-sparking, temperature-controlled accessories for Zone 2 areas under the increased safety philosophy. Common failures include overheating due to insufficient heat dissipation, surface discoloration indicating internal stress, and component loosening in vibration-prone environments.
Brass & Stainless Construction Components
Premium corrosion-resistant versions of Oldham enclosures for marine, pharmaceutical, and hygiene-sensitive applications. Degradation issues include dezincification in brass, stress corrosion cracking in stainless under chloride exposure, and galvanic corrosion at dissimilar metal junctions.

Common OLDHAM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in OLDHAM equipment arriving at our workshop.
- ✓Flange seal degradation and loss of flameproof integrity — Oldham enclosures experience flange seal failure due to repeated thermal cycling in furnace or kiln environments, UV exposure in outdoor installations, and incomplete sealing compound application during assembly. Chemical exposure in refineries can degrade elastomeric seals over 3-5 years.
- ✓Cable gland thread stripping and leaking seals — Oldham cable glands suffer thread damage when over-torqued (common in field installations lacking torque wrenches), or when installers use incorrect entry tools. Brass glands are particularly vulnerable; stainless steel glands strip under reversed assembly or aggressive maintenance.
- ✓Contact welding and arc tracking inside push button units — Oldham flameproof push buttons experience contact fusion when high fault currents flow during arc events in the hazardous area, or when contacts wear and develop high resistance. Repeated thermal stress in cyclic duty applications (furnace doors, compressor interlocks) accelerates contact degradation.
- ✓Corrosion and seizing of metric thread entries — Oldham enclosures installed in offshore platforms, coastal chemical plants, or high-humidity pharmaceutical facilities experience rapid corrosion of brass and mild steel components. Chloride ingress and galvanic coupling with stainless steel fasteners accelerates deterioration, causing threads to seize within 1-2 years.
- ✓Loss of ATEX certification due to improper field repairs — Plant technicians sometimes drill unauthorized holes, apply non-certified sealants, or source counterfeit replacement glands to reduce downtime, unknowingly voiding flameproof certification. Oldham equipment modified for quick fixes no longer protects against internal explosions or meets regulatory compliance.
- ✓Mechanical binding and corrosion of selector switch mechanisms — Oldham increased safety 'e' selector switches in mining or cement plants accumulate dust, moisture, and corrosion products inside the mechanism after years of exposure. Thermal cycling and vibration from heavy machinery cause internal springs to stick and detents to bind, preventing smooth rotation.

Frequently Asked Questions — OLDHAM Repairs
Does Synchronics repair Oldham explosion-proof equipment anywhere in India?+
Yes, absolutely. Synchronics has PAN-India repair coverage for the entire Oldham product range including flameproof enclosures, cable glands, push buttons, and terminal boxes. We operate from our main facility in Vadodara, Gujarat, with doorstep pickup available from Mumbai, Pune, Bangalore, Hyderabad, Chennai, Kolkata, Delhi, Ahmedabad, and all major Indian cities. All repairs are ATEX-compliant and certified.
Can you repair Oldham equipment and restore ATEX certification?+
Yes. Synchronics is certified to perform ATEX-compliant repairs on all Oldham flameproof and increased safety 'e' equipment. We maintain detailed inspection records, replace only genuine or certified alternative components, apply approved sealing compounds, and issue full ATEX certification documents upon completion. Your equipment returns with current compliance status and photographic repair evidence for regulatory audits.
What is the typical turnaround time for Oldham enclosure and gland repairs?+
Standard repairs like cable gland replacement or seal re-application typically take 3-5 working days from receipt. Complex flameproof enclosure restoration or custom component fabrication may require 5-10 days. We offer urgent express service for critical production lines; contact our emergency hotline for same-day diagnostics and expedited turnaround quotes specific to your Oldham equipment.
My Oldham junction box flange is damaged and losing its flameproof seal. Can it be repaired or must I replace it?+
Most Oldham flange damage can be repaired. Synchronics inspects the flange surface for cracks, corrosion pitting, and deformation. If the flange base metal is intact, we resurface, re-machine mating surfaces to specification, and re-seal per ATEX standards. Complete replacement is only necessary if cracking is deep, corrosion has consumed more than 50% material, or previous repairs have damaged structural integrity. We assess and provide cost-benefit analysis for repair versus replacement.
We use Oldham equipment in a coastal pharmaceutical plant with high salt-air corrosion. What preventative measures do you recommend?+
Synchronics recommends upgrading to stainless steel 316L versions of your Oldham glands and enclosures during maintenance cycles, applying additional marine-grade sealants, and implementing 18-month inspection intervals rather than the standard 24 months. We can also provide nickel-plated or passivated brass components as interim cost-effective upgrades. Detailed environmental assessment and material selection guidance are included with every coastal facility repair quote.
How do I send my OLDHAM 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 OLDHAM 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 OLDHAM 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 OLDHAM 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.
