Leengate Valves have agreed to sponsor the club's warm-up kit for the next two seasons.
The agreement extends the company's long association with the club. Leengate Valves sponsored the back of the shirts for nine years and they were also sponsors of the Legends Lounge until recently.
Commenting on the deal, Leengate Valves' managing director, Steve Pickering, said: "We thought the time was right to look at sponsoring something else at the club and we are delighted to maintain our involvement.
"The majority of our business is not local so we look for ways of promoting the company as the team travels around the country. When the players are out on the pitch, warming up, our name is going to be spotted."
Spireites commercial manager Jim Brown said: "Leengate Valves are valued sponsors and I would like to thank them for their continued loyal support, which is very much appreciated."
