Thermostat 750 F

[donfco]

Hi, excuse my English I am from Nuevo Laredo, Mexico, I am looking for a thermostat to 750 F , as a year and a half I'm doing my pizzas in my pizzeria with a high temperature ovens (made in home  ) but I have to controlling the temperature in manually form as in Mexico do not get a thermostat to this temperature, would appreciate if someone can help me 
the ovens are natural gas, low pressure...thanks

No sé de una adaptación del termostato de 750 grados. ¿Qué hace un técnico te diga? Ahora sólo tiene una válvula para controlar la llama?

Hola Don: he checado con diferentes proveedores de hornos incluyendo los de coriat y no pueden ayudarme, los que manejan quemadores industriales Moragas me dijeron que iban a hacer lo posible por investigarme este asunto pero no me dan ninguna respuesta, mis hornos los diseñe con un solo quemador en la parte de abajo similar a este http://www.cofaco.com.ar/detalle.php?id=7

Mi amigo, Lo siento pero Coriat y Moragas eran los dos proveedores que iba a recomendar. Tengo un horno de Coriat. Yo tenía el termostato cambiado pero me da 320C. grados solamente.

Maybe some of you folks north of Mexico might know of a supplier for a complete control unit that can go to 750F as my on line search lead nowhere. I'm not sure such a thing exists. The control box valve would have to have a pilot start position, with a thermocouple for the pilot and a thermosensor that would be mounted inside the oven to regulate the banjo burner via the thermostat. Thanks.

I don't know of anything pre-made, but I think you could make one pretty easily with a Old furnace gas valve for a standing pilot furnace and a PID temperature control unit.  I think they even make PID units that can output 24V to drive the valve, so you could even avoid a stand alone transformer. 

[buceriasdon]

Jeff, Do you think the PID could replace the hot water sensor on a water heater valve. I'm thinking the valve is a solenoid valve, correct? In my part of Mexico house heaters are unheard of but water heaters are not.

[shuboyje]

Not sure I would go there.  I'd hate to turn your water heater into a impromptu steam boiler.  A PID that can be set well above the boiling point of water would just be scary to me controlling a water heater, you aren't gonna find one not made in china, and you are one malfunction away from disaster.  I know water heaters have multiple safeties to avoid this, but am not familiar enough with them to say it is safe. 

All that said, if you wanted to do it you probably could the same way I mentioned for the oven.  I'd imagine you could control pretty much any gas appliance that way.

[buceriasdon]

Jeff, I hear you. I'm very concerned about creating a natural gas bomb by my attempts to help. That's not help. Thank you.

Hola, gracias por el apoyo, el personal de moragas ya se puso en contacto conmigo  y me comenta que no manejan un termostato de este tipo pero que se puede adaptar un pirómetro conectado por un termopar tipo j, y estos a una válvula selenoide que se encargue de abrir y cerrrar el paso del gas, por lo cual el siguiente paso es identificar los elementos que mejor se adaptan , su precio y las modificaciones necesarias en mi horno...saludos

Eso es bueno. Buena suerte.
