Preventative Maintenance for all Industrial Ovens, Furnaces, Aqueous Parts Washers and Ice Builders

Capital Equipment is a large investment for any company, and a lot of time and research is spent selecting and engineering the perfect solution for the application. After installation, preventative maintenance becomes an important element in maintaining the oven, furnace or washer. The life span may exceed 30 years if properly maintained.  Scheduling preventative maintenance is key to maintaining the maximum efficiencies of your equipment and the best way to avoid downtime. The Customer Support Services division at ITS is ready to assist! We offer one-stop support for service and parts.

The Customer Support Services team offers equipment audits, preventative maintenance, repairs and replacement parts. We service our equipment and the machines of our competitors. ITS starts with a complete audit of the machine and creates a list of needed service to maintain peak performance. By servicing our competitor’s equipment we are able to offer all-inclusive service to our customers which gives peace of mind that assistance is just a phone call away. Our technicians travel the globe and all are factory trained. Our team has been together many years and we continually train new team members to provide the exceptional service that is expected from ITS.

Worry free – Delivering Peace of Mind

Worry free maintenance plans are available. Our techs will inspect your industrial oven, furnace, aqueous washer or ice builder annually and replace any needed parts. With the plan, we will contact you to set up the audit so no worries of forgetting. Comprehensive Maintenance Plans deliver peace of mind! ITS also provides 24 hour service for all customers from our Emergency Response Team.

Our parts department will create complete parts kits for our customers. Order the kit with your Audit/Preventative Maintenance trip and we will have the parts onsite for the technician to replace at that time. Worry free and convenient.

Meet Brian, the ITS Service Coordinator. He will assist in setting up your service appointment:

Our goal is to provide the most comprehensive support for all thermal equipment in the industry. What can you expect in an ITS audit? Here is a shortened version of our extensive checklist:

Following are the procedures our Service Technician will go through when conducting a system audit/survey.

The following fan and bearing checks will be done as part of the system audit:
• The guarding on all fans will be removed and sheave alignments will be checked
• The fans’ actual running RPMs will be measured and recorded for each fan
• The bearings, as well as the belts, on these fans will be inspected
• All sheaves, sheave alignment, fan belts and motors will be inspected for normal wear
• The technical data of the fan and motor will be recorded and compared to the design metrics as well as the previous year’s metrics
• The bearings will be analyzed for excessive heat and vibration

The following electrical checks will be done as part of the system audit:
• Motor Data such as Horsepower, Full Load Amps and RPM will be measured and recorded
• The incoming Power to the main control panel will be measured and recorded
• The system wiring will be checked and verified
• The motor amp draws will be measured and recorded for all motors
• If unit is SCR controlled, the gain and bias conditions will be checked
• The VFD setup will be checked
• The process temperature controller, as well as high limit controllers
• A spreadsheet of all the parameters for the controllers will be created, if it does not already exist
• The control cabinet will be inspected for wiring issues such as over-heated wires, jumpers, damaged contactors and damaged relays
• All junction boxes and disconnect switches will be checked for over-heated wires and damaged switches
• All voltage, amperage , motor data, RPM’s will be recorded and verified against the design data and the previous year’s data
• All electric heating systems will be checked thoroughly, including the heat bank and control source
• All VFD’s will be checked for normal operation and all data will be recorded for future use
• All controllers will be analyzed for the proper parameters and control
• All of the electric metrics will be recorded for future comparison

The following are the safety checks that will be done as part of the system audit:
• All air flow switches will be checked for function and correct operation
• High / Low gas pressure switches will be verified (Gas units)
• All gas and vent valves will be checked for any leakage (Gas units)
• Thermocouple continuity will be verified

The following are the burner checks that are performed during the audit: (If the system is a gas unit)
• Air differential check – specific to the manufacturer and model of the burner
• Gas differential check – specific to the manufacturer and model of the burner
• The condition and functionality of the spark igniter, and flame rod or UV Scanner will be checked
• The integrity of the flame module will be verified and set up as needed
• Checking and cleaning, if necessary the internal components of the burner – burner blower wheel, perforated sheet
• Verifying all safeties on the associated gas train
• All system safeties devices will be verified, including but not limited to air flow switches, gas pressure switches, proof of closure switches, over temperature devices and flame supervision devices if warranted
• The burner system will be thoroughly checked, including cleaning the burner, cleaning or replacing the flame and spark rod and verifying the operation of the UV scanner if warranted
• The burner will be set up to factory settings for optimum efficiency

Additional items that will be checked during the oven audit to include:
• Inspection of the fan wheel clearances on each fan
• If system includes any pumps, they will be checked
• Checking and balancing the airflow of the oven
• Lubricating the bearings on the system and looking for any signs of wear
• Inspection of conveyor
• Checking gear boxes and gear oil
• If a PLC is in the system, a current copy of the program will be downloaded for ITS telephone support records and any necessary changes requested by customer may be made (Additional on site time may be required)
• Training customer’s maintenance personnel and operators on systems operation and maintenance

Additional system checks will include:
• Fan wheel inspection
• Pump inspection for excessive heat and vibration
• Bearing lubrication, including inspection and proposing a revised maintenance schedule if necessary
• Inspection of all gear boxes
• Inspection of the part transport systems; including the mats, chains, sprockets, shafts, rollers and slide beds
• Download the current PLC and HMI program from the machine to help support the customer via the telephone
• Comprehensive training for operation and maintenance

As you can see, this is a comprehensive list! A detailed Service Report, parameter sheets and all settings will be documented and a copy supplied to the customer upon completion of the trip. In order to ensure customer satisfaction, the CSS team will send customer surveys after every service call.
