The GR45 comes equipped with a manual control thermostatic feature, which allows for precise temperature adjustments, ensuring perfect cooking for various menu items. Its stainless steel construction not only guarantees durability but also makes cleaning a breeze.

In contrast, the GR65 offers a larger cooking surface, measuring 65 inches. This model is particularly well-suited for establishments with high-volume demands.
