Hi Marc,

When you spoke to the salesperson, did you tell them that the connecting
wires must be at least 8 feet long?

Thank you,
Albert

>> Hi Albert,
>>
>> Here is the email from the manufacture. These can run at 250C
>> continuously. The main point is that we have a quote for units which can
>> be purchased for testing at 250C to confirm if this will work.
>>
>> We are still looking for other options.

>> Hello,
>>
>>
>>
>> I have just left you a voice mail on this project.
>>
>>
>>
>> We are comfortable with having the heaters quoted here run at 250C on a
>> continuous basis.​
>>
>>
>>
>> Some of the construction has been changed:
>>
>>
>>
>>   *   Wire wound heating element
>>   *   High Temperature Silicone Rubber
>>   *   Not a UL approved and stamped heater
>>
>>
>>
>> We’d still have a maximum of (12) heaters which can be connected
>> together in parallel.
>>
>>
>>
>> I’ve shown the cost of having (10) Heaters Expedited on our Fast Track
>> Service.
>>
>> Any questions please let me know!!
