Can the coolant shells of the BioPak 240R be filled with ice cubes instead of using the ice canister?
NO. The use of coolants other than what is specified by the manual will violate the certification of the BioPak. The use of ice cubes will also result in reduced cooling capacity as it will be impossible to pack as much ice density into the coolant shell using ice cubes as is possible with the ice canister. The use of ice cubes in the coolant shells will also result in the loss of cold melt water from the coolant shells as the shells are not sealed against such leakage. The loss of melt water will further reduce cooling capacity as compared to the ice canisters. Finally the use of ice cubes in place of the ice canister will result in cold melt water running down the BioPak to be deposited on the back on the user, soaking the pants and legs.
