if there is no gas-fired unit nearby, I'll have to make a separate pipe for you, and the cost will certainly be high. In addition, the pressure requirement of catering is relatively high, and it will be higher if it is equipped with a voltage regulator alone. Then look at the equipment list. If the voltage regulator is imported, you can ask to change it to domestic one, and if the buried pipeline is replaced by overhead one, the cost will also be lower.
