Medical Equipment Repair & Servicing
HNLMD Services provides comprehensive repair and preventive maintenance programs for a wide range of biomedical and surgical equipment. Our certified technicians are trained to diagnose and resolve mechanical, electrical, and software-related issues across all major equipment categories.
We understand that equipment downtime directly impacts patient care and operational efficiency. That's why we prioritize rapid response times and carry a broad inventory of common replacement parts — allowing us to complete most repairs in a single visit.
Our preventive maintenance programs are structured to meet manufacturer recommendations and The Joint Commission (TJC) and AAMI standards, helping your facility stay compliant while extending the service life of your equipment investments.
Autoclave Chamber Cleaning
Over time, autoclave chambers accumulate mineral scale, protein deposits, and biological residue that degrade sterilization performance and damage chamber surfaces. HNLMD Services offers professional autoclave chamber cleaning using validated, healthcare-grade chemical processes.
Our cleaning protocol includes complete chamber inspection, scale and deposit removal, gasket and door seal assessment, drain strainer cleaning, and a final performance verification cycle using a calibrated data logger to document autoclave performance. We document all findings and provide a detailed service report for your records.
Regular autoclave chamber cleaning improves sterilization efficacy, reduces equipment failures, and extends the service life of your sterilizers — making it one of the most cost-effective maintenance investments a sterile processing department can make.
Sterile Environment Rust Removal
Rust and corrosion in sterilization environments are more than aesthetic problems — they can compromise sterility, damage equipment, and create compliance findings during inspections. HNLMD Services specializes in safe, effective rust removal for sterilizers, chamber walls, racks, carts, and associated sterile processing equipment.
We use medical-grade descaling and rust conversion agents that are safe for use in clinical environments and do not leave harmful residues. Our process is carefully controlled to protect surface integrity while eliminating corrosion at its source.
After rust removal, we can apply protective coatings or recommend surface treatments to inhibit future oxidation — keeping your sterile processing environment clean, compliant, and visually professional.
Sterilizer Maintenance & Repair
Steam sterilizers are among the most critical pieces of equipment in any healthcare facility. When they go down, your surgical and sterile processing workflows come to a halt. HNLMD Services provides comprehensive maintenance and repair services for steam (gravity and pre-vacuum) and dry-heat sterilizers.
We service equipment from all major manufacturers including Getinge, Steris, Tuttnauer, Belimed, and Midmark. Our technicians are trained on both legacy and current-generation systems, and we maintain access to genuine OEM and high-quality aftermarket parts.
In addition to reactive repairs, we offer scheduled preventive maintenance contracts that include annual safety testing, calibration, door gasket replacement, chamber inspection, and verification testing — giving your facility peace of mind and a clear compliance record.
Flat Rate Troubleshooting
Uncertain about what's wrong with your equipment? Our flat-rate troubleshooting service gives you a clear, upfront cost for a comprehensive diagnostic evaluation — no surprise labor charges or inflated invoices. We believe in transparent pricing because trust is the foundation of every service relationship.
During a flat-rate troubleshooting visit, our technician will perform a systematic diagnostic evaluation of the equipment in question, identify the root cause of any malfunction, and provide a detailed written assessment with repair options and associated costs.
If you choose to proceed with repairs following the diagnostic, the troubleshooting fee is credited toward your repair invoice. This approach ensures you always have the information needed to make an informed decision — without financial pressure.
Remodeling
From surface refinishing and repainting to cosmetic restoration of equipment exteriors, HNLMD's remodeling services return aging medical equipment to a clean, professional appearance.
We use medical-grade, hospital-compatible coatings formulated to withstand disinfectants, steam, and high-humidity clinical environments. Our preparation process includes thorough cleaning, priming, and controlled application to ensure a durable, uniform finish.
Whether it's a single unit or a fleet of sterile processing carts, we restore the look and extend the service life of your equipment — without taking it out of your facility for extended periods.
Case Cart Maintenance for SPDs
We inspect, clean, and service case carts used in Sterile Processing Departments (SPDs), ensuring they remain functional, rust-free, and compliant with sterile field requirements.
Services include frame inspection, hinge and latch repair, liner assessment, and surface treatment to protect against corrosion in high-humidity sterilization environments.
Well-maintained case carts reduce cross-contamination risk and keep your SPD workflows running smoothly — a simple investment that pays off every time a cart hits the OR.
ST108 Prep and Monitoring
HNLMD supports your team with proper preparation and monitoring procedures following AAMI ST108 guidelines for water quality in steam sterilization.
We assess water quality parameters, assist with documentation, and help ensure your steam sterilization process meets current AAMI and Joint Commission (TJC) standards.
Proper water quality is essential to sterilizer longevity and cycle efficacy. Poor water chemistry is one of the leading causes of chamber scale, corrosion, and sterilization failures — ST108 compliance protects your equipment and your patients.
Caster Replacement
Worn or broken casters on medical carts, case carts, and sterile processing equipment are a safety hazard and an infection control concern.
We replace casters on all types of medical-grade rolling stock — including locking casters, swivel casters, and specialty sterile processing cart casters — quickly and affordably.
Don't let a broken caster take equipment out of service. We carry a broad inventory of healthcare-grade casters and can complete most replacements on-site in a single visit.
Autoclave Validation through Calibrated Data Logger
We provide documented autoclave validation using NIST-traceable calibrated data loggers, producing a performance record suitable for Joint Commission (TJC) and AAMI compliance documentation.
Validation is recommended after installation, relocation, major repairs, or as part of your annual preventive maintenance program. Our validation reports are formatted to support your facility's compliance records.
Knowing your autoclave is performing within validated parameters — not just passing a Bowie-Dick test — gives your facility confidence and gives your accreditation surveyors exactly what they need to see.
