Sub-Zero is ice management software developed by Marmak. It tracks resurfacing cycles, flood logs, surface depth checks, and maintenance records in one place — giving rink operators a clear, running picture of what their ice is doing and what it needs.

CTM Services is an authorized Sub-Zero reseller. We carry it because it pairs naturally with Olympia equipment and gives our customers a practical way to manage ice quality alongside their resurfacer maintenance. We can get you set up and are available if questions come up along the way.
