How do you measure the offset of a door?

How do you measure the offset of a door?

hinge offset Latch offset

measuring a hinge offset measuring a latch offset
The offset of a door is the distance between the door jamb and the outside surface of the door. Figure one shows the offset from a top view of the door and jamb assembly. The other drawings show the offset of common kinds of hardware. If the door surface is even with the door jamb, the door has no offset and we say the door is "Flush".

Figure one shows a left hand cam-lift hinge assembly. Remove the strap ( the part that mounts on the door) from the butt ( the part that mounts on the frame) and remove the pin assembly (figure 2).

Pop out the cap and re-insert the pin assembly on the opposite side of the blade (figure 3).

Now turn the blade 180 degrees (figure4).

fig.5
Re-insert the blade into the butt and replace the cap (figure 5). Your hinge is now ready to be mounted on a right hand door.

The same principle applies to an edgemount cam-lift hinges used on reach-in equipment. On an edgemount hinge the part that mounts to the frame of the cabinet is called the cabinet wing. The part that mounts to the door is called the door wing. To reverse edgemount hinges turn the cam (plastic piece mounted in the cabinet wing) 180 degrees.

All of the hinges we sell are reversible unless indicated otherwise in the catalog.

How do I determine if the door is left hand or right hand?

How do I determine if the door is left hand or right hand?
When facing the unit from the outside, if the hinges are mounted on the right,it is considered right-hand hinged.

How do you calculate watts per Foot?

How do you calculate watts per Foot?

This is an important calculation when engineering the warmer wires that go around walk-in doors to keep them from developing condesation and then freezing shut.

Let's assume we have a 24' length of 4 ohms per foot wire that we're going to connect to 115V current...

1. Calculate the total resistance =

  • Ohms/ft x number of feet.=
  • 24 X 4 = 96

2. Calculate the total wattage =

  • voltage squared / total resistance =
  • (115 x 115) / 96 =
  • 137.76

3. Calculate Watts per Foot =

  • total wattage / number of feet =
  • 137.76 / 24 =
  • 5.74
  • Generally we engineer our warmer wires to operate between 6 and 9 watts per foot.

    Because the watts per foot is very sensitive to the wire length we do not recommend reducing the length of warmer wires in the field. It the wire gets too short, the watts per foot will get hot enough to burn the wire.

Why do you get one quarter of the watts when you connect a 230V heater to 115V?

Why do you get one quarter of the watts when you connect a 230V heater to 115V?

Folks think that if you reduce the voltage in half, the total wattage is reduced in half as well. As we'll see, those folks are wrong!

Let's take a heater thats rated at 1000W on 230V and calculate it's wattage when it's connected to 115V...

1. Calculate the total resistance =

  • Voltage squared / rated wattage =
  • (230 x 230) / 1000 =
  • 52.90

2. Calculate the wattage when connected to 115V =

  • Voltage squared / total resistance =
  • (115 x 115) / 52.90 =
  • 250

You can connect heaters rated at 230V to 155V service all day long if your content with 1/4 of the rated wattage.

However, you should not connect a heater rated at 115V heater to 230V (unless wired in series as pairs), since they will likely burn out. After all, they'll be operating at wattages 4 times greater than what they were designed.

What's the difference between connecting heaters in series and in parallel?

What's the difference between connecting heaters in series and in parallel?
in series
In Series

When connected in series, two heaters of equal wattage, connected to the voltage at which they are rated, will generate 1/2 the wattage of one of the heaters. For example, two 1000 watt , 230 volt heaters connected in series to 230 volt output 500 watts total.

Also, two heaters of equal wattage, rated at 115 volt and then connected in series to 230 volt service, will generate twice the wattage of one of the heaters. For example, two 500 watt , 115 volt heaters connected in series to 230 volt output 1000 watts. Remember DO NOT connect 115 volt heaters to 230 volt unless they are connected in series. We recommend that when connecting heaters in series, you always use heaters rated with the same voltage and wattage. The calculations for figuring circuit outputs with unequal resistances can be mind bending.




in parallel
In Parallel

When you connect two heaters in parallel, it has the effect of summing the wattages. For example, two heaters each rated at 230 volts and 1000 watts when connected in parallel to 230 volts will generate 2000 watts total. If the same heaters are connected in parallel to 115 volts, then the output will be cut to 1/4 or 500 watts.

What's the difference beween a defrost termination and a defrost limit switch?

What's the difference beween a defrost termination and a defrost limit switch?

Many people in the refrigeration trade think these two switches are the same but in fact they behave in exactly the opposite way.

  • A defrost termintion closes on temperature rise to energize the solenoid on the time clock which terminates the defrost cycle.

  • A defrost limit switch opens on temperature rise and acts as a safety swich to turn off the defrost heater if the coil is getting too warm.

Accounting

Why no credit application?

New customers are often amazed to learn that Case Parts has no credit application and will generally open a Net 30 day account over the phone. We trust our trade customers to honor their obligations much in the same way our customers trust us to provide them with prompt professional service. It's our philosophy that mutual trust is basis of all successful business relationships and we see our "no hassle" credit policy as the first way we demonstrate our commitment to our customers.

When do you send statements?

Unless requested, we only send statements to customers whose accounts are more than 14 days overdue. Because we have thousands of customers across the nation and mail statements twice a month, sending statements to everyone would be increase our overhead and interfere with our ability to keep our prices at rock bottom. We prefer customers to pay from the invoice.

How do finance charges work?

Our computer calculates a finance charge of 3/4 of 1 percent on a customer's overdue balance and adds it to their account as a separate entry. Finance charges are assessed twice each month, immediately prior to the mailing of statements - generally the 5th and 20th of each month.

Who do I call if I have a or question with my account?

If you have a question about a particular invoice, you should call the office with which you placed your order. If you have a question about your account, your balance, your status, or if your would like to receive a monthly statement call our Los Angeles office.
