Choosing the Right Coil Upender
A Coil Upender is used to increase the airflow capacity of a system by adding a parallel coil to the pipe or fitting. Adding a coil upender will eliminate the need to sling heavy coils over the exterior of your system. Many design professionals will suggest that you install a coil straightener if your heating and air conditioning systems have aged out and are in need of an upgrade. Contact product experts to locate the perfect solution for your particular system.
There are three common methods for installing a Coil Upender: uncoiling, adding a spiral uncoiling wrap, or a combination of both techniques. For uncoiling, the heated coil wire is removed from the air handling system (usually located above the coils). A heavy duty blower removes the air from the system. Uncoiled coils are placed into a collection loop. The collection loop contains a thermostatically controlled thermostat and valve which allow the coil to slowly draw in fresh air.
Some coil upenders are provided with the option of supplying your system with a lubrication guide, which helps to ensure that the coils are correctly lubricated during processing. With uncoiling, the hot and cold air coils are placed in a spiral wrapping process. The wrapping process creates a low-resistance path for the warm air to flow through. Once the flow of air is slow, a pressure gauge on the control panel will indicate that the system is receiving adequate cool air.
Adding a spiral upender provides a series of concentric circles with which to support the coils. These concentric circles provide a smooth and uniform support for the coils when they are being installed or when the heaters or air conditioners are operating. When a coil handling unit is placed in an area where the heat is extremely cold, there is a possibility of the unit collapsing, due to expansion of the coils and the supporting rollers. If the upper feed rollers become under heated, the coils can become damaged, which could prevent them from running efficiently. Therefore, it is important that you select coil lenders with the appropriate feed rolls.
The most common types of coil upenders are those which incorporate a pre-installed helical screw arrangement. These screws allow the coiled spring to be secured into place once the coiling process has begun. Other types of coil fenders incorporate the use of a ball bearing clamp system, which is controlled via a screw threading mechanism. When the screws are engaged, the bearings spin freely, providing a safe and reliable way to uncoil the coils.
Coil upenders are also available in a pinch roller setting. When the heat is applied to the coil, the spiral coils are forced to move in a direction perpendicular to the surface they are placed on. These pinch rolls are a popular option for electrical wire stripping because they provide excellent conductivity rates, along with high electrical strength. The only downside is that these pinch rolls are unable to support as much weight as the straighteners, so the coiled spring may need to be replaced if the wire is too heavy. Another option available for uncoiling coils is a ratchet system. These systems have two speed settings, which enable the user to increase or decrease the electrical current through the coil using a ratchet.
