Q. At what temperature do I need to keep pharmaceuticals ?
A. Under Federal guidelines, (United States Pharmacopeia 24 / NF 19-2000) even pharmaceuticals that are meant to be stored at “room temperature” require a temperature controlled environment when stored in a vehicle. “Room Temperature” is defined as 68° to 77° F. You should check with your pharmaceutical manufacture or supplier to determine what the storage temperature requirements are for other drugs.
Q. How much current does the E-Cab draw ?
A. When operating on 12 volt vehicle power, the E-Cab draws approximately 4 amps when the heater or refrigeration is operating. While maintaining a 40 degree temperature difference between inside and outside temperature, the heating or refrigeration system only needs to operate about 30% of the time. Thus the long term average current draw would be only 1.3 amps.
Operating from 120 volt shore power, the E-Cab will draw less than 1/2 amp while the refrigeration or heater is in operation.
Q. Does the E-Cab use a Thermo-Electric Cooler (TEC) ?
A. No, The E-Cab uses a true compressor driven refrigeration system for cooling. A TEC is effective for cooling very small areas such as computer chips and thermo imaging sensors but too inefficient for cooling larger spaces. A TEC based system can only cool a cabinet 20 to 30 degrees at best, and would have to draw over 10 amps continuously to do that. The refrigeration system used in the E-Cab and ECS-15 can cool over 70 degrees and would only draw a maximum of 4 amps.
Q. Will the E-Cab operate from my vehicle’s shore power converter ?
A. Yes, the E-Cab can operate from a 12 volt converter but a better solution is to use the E-Cabs Tri-Voltage Option. With this option installed, the E-Cab will automatically switch between 12 volt vehicle power and 120 or 240 volt shore power without the use of an external converter.
Q. Can I operate the E-Cab from my vehicle’s 120 volt AC generator ?
A. With the Tri-Voltage Option, the E-Cab can operate from a 120 or 240 volt generator. If generator power becomes un-available, the E-Cab will automatically switch to the vehicles 12 volt power system.
Q. How do I change the temperature inside my E-Cab ?
A. To change the set point temperature, simply press the SET TEMP button. The display will now read the current set-point temperature. Use the WARMER or COOLER buttons to change the temperature. A few seconds after making the changes, the display will change back to the actual temperature inside the E-Cab and the new set-point will be stored in the E-Cabs memory.
Q. Do I need to defrost my E-Cab ?
A. No. Under high humidity and low set-point temperatures (below 50 degrees), ice can form on some of the cooling components inside the E-Cab. The E-Cab detects when these conditions exists and will automatically go into a defrost cycle. The defrost cycle will, at most, only run once every 12 hours and lasts about 10 minuets. An indicator on the control panel will illuminate when the E-Cab is in a defrost cycle.
Q. How much space can I cool with an ECS-15 ?
A. The ECS-15 is used to maintain temperature in your own custom designed cabinet. In a properly insulated cabinet with a good door seal, the ECS-15 can cool over 5 cubic feet of storage space.
Q. Do I need to set my E-Cab to heating in the winter ?
A. The E-Cab will automatically turn on the heater or refrigeration as needed to maintain the set-point temperature. No user intervention is required.
Q. What is United States Pharmacopeia 24 / NF 19-2000 ?
A. United States Pharmacopeia 24 / NF 19-2000 states the temperature requirements for storing pharmaceuticals. In part, it states:
Controlled Room Temperature - A temperature maintained thermostatically that encompasses the usual and customary working environment of 20° to 25° (68° to 77° F); that results in a mean kinetic temperature calculated to be not more than 25°; and that allows for excursions between 15° and 30° (59°and 86° F) that are experienced in pharmacies, hospitals, and warehouses. Articles may be labeled for storage at "controlled room temperature" or at "up to 25°", or other wording based on the same mean kinetic temperature. The mean kinetic temperature is a calculated value that may be used as an isothermal storage temperature that simulates the nonisothermal effects of storage temperature variations.
