The phrase "at a temperature equal" is correct and usable in written English.
It can be used in scientific or technical contexts when discussing conditions that are the same in terms of temperature.
Example: "The experiment was conducted at a temperature equal to 25 degrees Celsius to ensure consistency in results."
Alternatives: "at an equal temperature" or "at a uniform temperature".
