Steel Mill Cooling Tower Fan Support

            Multiple Horner Industrial Divisions worked together to secure a fan on a cooling tower for the Steel Mill customer. Air conditioning equipment and industrial processes can generate heat in the form of tons of hot water that needs to be cooled down. That’s where an industrial cooling tower comes in. Overheated water flows through the cooling tower where it’s recirculated and exposed to cool, dry air. Heat leaves the recirculating cooling tower water through evaporation. This is called evaporative cooling. The colder water then reenters the air conditioning equipment or process to cool that equipment [...]

Horner Springfield: Sulzer Pump Company Repair Center

          There is an old saying that when you mix water and electricity, water will always win. Judging from the amount of submersible work that the Horner Springfield division has been receiving, I would say that the old saying is very true. We have seen a substantial increase in the number of underwater submersible pumps and agitators that have a motor, gearbox and fan. Part of the reason for the increase in this line of repair work is the long lead time for replacement units. Underwater submersible equipment that our division has repaired ranges in size from [...]

Locker Manufacturer Fan Failure

A locker manufacturer in Illinois builds lockers like you would see in schools and employee work areas. They called Horner because they had a fan failure and it caused enough damage to need to be replaced. This fan is part of an oven application that dries the painted locker panels. The fan failed due to fatigue and the fan blades came off and destroyed the fan cone. When this fan was originally built it was installed without consideration of it ever being replaced or repaired. A double wall had to be cut and removed to allow the job to be accomplished. [...]

Hardwood Manufacturer 50″ Fan

A hardwood flooring manufacturer contacted Horner about repairing a 50” Fan. With help from Indianapolis Field Service, Horner Fan and Fabrication had a 3 day window to repair this 50” fan wheel. This was the main dust collection fan for the plant. The structure around this fan made it very challenging to remove. The fan is inside the plant with structural steel above the fan and a concrete wall on two sides. After removing the insulation and the inlet fitting there was about 36” of space to maneuver this heavy wheel and 2-15/16” shaft out of the building. Once in the [...]

Rooftop Exhaust Fan Safety Project

A customer who makes counter weights for fork trucks called Horner after a safety incident. One of their old exhaust fans has a failure and a blade from the prop fell to the manufacturing floor. The customer knew they not only had to replace the roof- top fans but needed to rethink the design for safety of the workers. So instead of 1 fan being repaired they decided all 4 rooftop exhaust fans would be redesigned. Fan and Fabrication came up with an aluminum safety screen that would be welded on the underside of the fans. This new custom safety screen [...]

Powerplant Turbine Vent Fan/Motor

A power plant’s combined cycle generating station contacted Horner Salesperson Joseph Motz on Friday 12/16/22 regarding one of the Turbine Vent fan motors which had failed and was going to need to be replaced or repaired. As this motor is not accessible while the Turbine generator is running, Horner could not verify Motor dimensions for the possible replacement of the original OEM motor. The Station had a spare fan, but it did not come with a motor. Upon inspection of the fan and Impeller in the customers storeroom, it was noted that the base could accommodate the metric frame motor but [...]

Zoo Emergency

A local zoo called, they have their main surgery room fan that is down, and they have surgeries to do. On the fan the bearing base was thin sheet metal, it was all busted up and the bearing was hanging almost upside down on the shaft, it was just a total mess! I convinced Frankie, one of our newer Field Service Technicians to ride along. He was excited and ready to see what surprises we would find. I was able to call the customer and get all the measurements I asked for. This all seemed to be going too easy and [...]

Vibration Issue on Forced Draft Fan

A 100 year old steam plant was having a long standing vibration issue that they could not correct. Our EMDS department determined the likely issue was the hub to shaft fit. Horner Machining Services did most of the work on this fan including: • Remove old bearing, couplings, and louvers • Press old shaft out of the fan • Sand blast the fan and louvers clean • steam clean coupling • set up new shaft and check for straightness, then install • Dynamic Balance • Paint and reinstall the original coupling Field Service did the on-site work for removal, installation, and [...]

Out Of Production Lock Nuts

One of Horner’s customers is a major supplier of automotive grade aluminum for major manufacturers of car and truck bodies. After the aluminum passes through a set of rolling mills to reduce the material thickness, the sheet passes through an annealing furnace to reduce material stresses from the rolling process. The annealing furnaces have fans circulating the furnace hot air to evenly distribute the heat to prevent hot spots. This particular fan assembly from one of the annealing furnaces had experienced a bearing failure. The shaft was initially sent to Horner Washington St to evaluate the damage to the main shaft. [...]

Lime and Stone ID Fan

A Lime and Stone Plant called in a panic that one of their Kiln ID Fans has an inboard bearing failure that caused extensive damage to the shaft. The Kiln ID Fan is a key element in this company’s production process, so they needed a quick turnaround. Our team procured the proper shaft material and Machining Services manufactured a new shaft. As a result of Horner’s great vendor relationships, Horner’s purchasing department secured new replacement bearings in record time. The fan was restored and balanced, then assembled with new shaft, bearings, RTDs and the coupling hub. The fan was delivered in [...]
